ACS Pharmacol Transl Sci 2024; 7:2827-2839. [PMID: 39296272 PMCID: PMC11406687 DOI: 10.1021/acsptsci.4c00331] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2024] [Revised: 07/26/2024] [Accepted: 07/31/2024] [Indexed: 09/21/2024]
Abstract
Ubiquitination is a post-translational modification that elicits a variety of cellular responses. Deubiquitinases (DUBs) remove ubiquitin moieties from proteins and modulate cellular processes by counteracting the ubiquitin ligase activities. Ubiquitination and deubiquitination processes are tightly regulated by different mechanisms and their dysregulation is associated with many diseases. Discovery of DUB inhibitors could not only lead to therapeutics but also facilitate the understanding of ubiquitination/deubiquitination processes and their regulatory mechanisms. To enable the inhibitor discovery against DUBs, we developed a cell-based DUB assay that utilizes a cell-permeable ubiquitin probe, Biotin-cR10-Ub-PA, to covalently label DUBs in their native cellular environment. Amplified luminescent proximity homogeneous assay (Alpha, specifically AlphaLISA) is utilized to quantitatively assess the capture of the target DUB by the Biotin-cR10-Ub-PA probe. We demonstrated that this new cell-based DUB assay is robust and amenable to high-throughput screening. Human USP15 was selected as a DUB of interest and screened against a library of protease inhibitors as a proof of concept. In addition to the widely adopted pan-DUB inhibitor PR-619, several other DUB inhibitors from the library were also identified as hits. This new DUB assay can be readily adapted for inhibitor discovery against many other human DUBs to identify potent and cell-permeable inhibitors.

Abstract
Latent bioreactive unnatural amino acids (Uaas) have been widely used in the development of covalent drugs and identification of protein interactors, such as proteins, DNA, RNA and carbohydrates. However, it is challenging to perform high-throughput identification of Uaa cross-linking products due to the complexities of protein samples and the data analysis processes. Enrichable Uaas can effectively reduce the complexities of protein samples and simplify data analysis, but few cross-linked peptides were identified from mammalian cell samples with these Uaas. Here we develop an enrichable and multiple amino acids reactive Uaa, eFSY, and demonstrate that eFSY is MS cleavable when eFSY-Lys and eFSY-His are the cross-linking products. An identification software, AixUaa is developed to decipher eFSY mass cleavable data. We systematically identify direct interactomes of Thioredoxin 1 (Trx1) and Selenoprotein M (SELM) with eFSY and AixUaa.

Abstract
Studying functional protein delivery into live cells is important, ranging from fundamental research to therapeutics. Cell-penetrating peptides (CPPs) are known to deliver proteins with applauded efficacy and have gained importance for applications in protein therapeutics and exploration of versatile cellular mechanisms. The primary aim of the work is to design a CPP as a tool and delivery vehicle for macromolecules, including proteins. In this work, boronic acid-linked cyclic deca arginine (cR10) is reported as an efficient CPP that exhibited 3-fold higher delivery of chemically synthesized ubiquitin (Ub) than pristine cR10-linked Ub, examined with live U2OS cells. As a futuristic plan, an artificial intelligence machine learning-based rationale has been designed and proposed.

Abstract
Ovarian cancer is the second most common cause of gynecologic cancer death. Chemoresistance and metastasis remain major challenges for current treatment. Previously, HAPSTR1 was shown to be a target gene of a paclitaxel resistance-associated miRNA. However, the biological function and underlying molecular mechanisms of HAPSTR1 in ovarian cancer progression remain unclear. Herein, we aimed to measure HAPSTR1 expression in ovarian cancer specimens and examine its correlations with clinical features and key functional interactions with other genes and proteins. An immunohistochemistry assay showed that HAPSTR1 was overexpressed in ovarian cancer tissues and was significantly associated with the FIGO stage and clinical outcome. HAPSTR1 overexpression promoted proliferation, invasion and migration in cellular and mouse models, whereas inhibition induced the opposite effects. In addition, HAPSTR1 stimulated the EMT pathway and affected the expression of autophagy biomarkers. Mechanistically, we demonstrated that HAPSTR1 is bound to LRPPRC and PSMD14 via immunoprecipitation. HAPSTR1 suppressed LRPPRC ubiquitination and recruited PSMD14 to interact with LRPPRC. Moreover, LRPPRC knockdown reversed HAPSTR1-mediated improvement in cellular proliferation, invasion, and migration. Our study is the first detailed and comprehensive analysis of HAPSTR1 in cancer progression and offers an experimental basis for the clinical treatment of ovarian carcinoma.

Abstract
Activity-based ubiquitin probes (Ub-ABPs) have recently been developed as effective tools for studying the capabilities of E1-E2-E3 enzymes, but most of them can only be used in cell lysates. Here, we report the first cell-penetrating Ub-Dha probes based on thiazolidine-protected cysteines, which enable successful delivery into cells confirmed by a fluorophore at the N-terminus of Ub and live-cell fluorescence microscopy. A total of 18 E1-E2-E3 enzymes in live cells were labelled and enriched in combination with label-free quantification (LFQ) mass spectrometry. This work provided a new cell-penetrating Ub tool for studying the activity and function of Ub-related enzymes.

Abstract
Deubiquitinases (DUBs) are a family of >100 proteases that hydrolyze isopeptide bonds linking ubiquitin to protein substrates, often leading to reduced substrate degradation through the ubiquitin proteasome system. Deregulation of DUB activity has been implicated in many diseases, including cancer, neurodegeneration and auto-inflammation, and several have been recognized as attractive targets for therapeutic intervention. Ubiquitin-derived covalent activity-based probes (ABPs) provide a powerful tool for DUB activity profiling, but their large recognition element impedes cellular permeability and presents an unmet need for small molecule ABPs which can account for regulation of DUB activity in intact cells or organisms. Here, through comprehensive chemoproteomic warhead profiling, we identify cyanopyrrolidine (CNPy) probe IMP-2373 (12) as a small molecule pan-DUB ABP to monitor DUB activity in physiologically relevant live cells. Through proteomics and targeted assays, we demonstrate that IMP-2373 quantitatively engages more than 35 DUBs across a range of non-toxic concentrations in diverse cell lines. We further demonstrate its application to quantification of changes in intracellular DUB activity during pharmacological inhibition and during MYC deregulation in a model of B cell lymphoma. IMP-2373 thus offers a complementary tool to ubiquitin ABPs to monitor dynamic DUB activity in the context of disease-relevant phenotypes.

Abstract
Dynamic monitoring of intracellular ubiquitin (Ub) conjugates is instrumental to understanding the Ub regulatory machinery. Although many biochemical approaches have been developed to characterize protein ubiquitination, chemical tools capable of temporal resolution probing of ubiquitination events remain to be developed. Here, we report the development of the first cell-permeable and stimuli-responsive Ub probe and its application for the temporal resolution profiling of ubiquitinated substrates in live cells. The probe carrying the photolabile group N-(2-nitrobenzyl)-Gly (Nbg) on the amide bond between Ub Gly75 and Gly76 is readily prepared through chemical synthesis and can be delivered to live cells by conjugation via a disulfide bond with the cyclic cell-penetrating peptide cR10D (i.e., 4-((4-(dimethylamino)phenyl)-azo)-benzoic acid-modified cyclic deca-arginine). Both in vitro and in vivo experiments showed that Ub-modifying enzymes (E1, E2s, and E3s) could not install the Ub probe onto substrate proteins prior to removal of the nitrobenzyl group, which was easily accomplished via photoirradiation. The utility and practicality of this probe were exemplified by the time-resolved biochemical and proteomic investigation of ubiquitination events in live cells during a H2O2-mediated oxidative stress response. This work shows a conceptually new family of chemical Ub tools for the time-resolved studies on dynamic protein ubiquitination in different biological processes and highlights the utility of modern chemical protein synthesis in obtaining custom-designed tools for biological studies.

Abstract
Flourished in the past two decades, fluorescent probe technology provides researchers with accurate and efficient tools for in situ imaging of biomarkers in living cells and tissues and may play a significant role in clinical diagnosis and treatment such as biomarker detection, fluorescence imaging-guided surgery, and photothermal/photodynamic therapy. In situ imaging of biomarkers depends on the spatial resolution of molecular probes. Nevertheless, the majority of currently available molecular fluorescent probes suffer from the drawback of diffusing from the target region. This leads to a rapid attenuation of the fluorescent signal over time and a reduction in spatial resolution. Consequently, the diffused fluorescent signal cannot accurately reflect the in situ information of the target. Self-immobilizing and self-precipitating molecular fluorescent probes can be used to overcome this problem. These probes ensure that the fluorescent signal remains at the location where the signal is generated for a long time. In this review, we introduce the development history of the two types of probes and classify them in detail according to different design strategies. In addition, we compare their advantages and disadvantages, summarize some representative studies conducted in recent years, and propose prospects for this field.

Abstract
The transiently-activated SUMO probes are conducive to understand the dynamic control of SENPs activity. Here, we developed a photocaged glycine-assisted strategy for the construction of on demand-activated SUMO-ABPs. The light-sensitive groups installed at G92 and G64 backbone of SUMO-2 can temporarily block probes activity and hamper aspartimide formation, respectively, which enabled the efficient synthesis of inert SUMO-2 propargylamide (PA). The probe could be activated to capture SENPs upon photo-irradiation not only in vitro but also in intact cells, providing opportunities to further perform intracellular time-resolved proteome-wide profiling of SUMO-related enzymes.

Abstract
Protein post-translational modifications (PTMs) regulate nearly all biological processes in eukaryotic cells, and synthetic PTM protein tools are widely used to detect the activity of the related enzymes and identify the interacting proteins in cell lysates. Recently, the study of these enzymes and the interacting proteome has been accomplished in live cells using cell-permeable PTM protein tools. In this concept, we will introduce cell penetrating techniques, the syntheses of cell-permeable PTM protein tools, and offer some future perspective.

Abstract
Proteases (proteolytic enzymes) are proteins that catalyze one of the most important biochemical reactions, namely the hydrolysis of the peptide bond in peptide and protein substrates. Therefore these molecular biocatalysts participate in virtually all living processes. The proper balance between intact and processed protease substrates enables to maintenance of homeostasis from a single-cell level to the whole living system. However, when the proteolytic activity is altered, this delicate balance is disturbed, which might lead to the development of a plethora of diseases. Given this, monitoring proteolytic activity is indispensable to understanding how proteases operate in disease lesions and how their altered catalytic activity might be harnessed for a better diagnosis and treatment. In this manuscript, we provide a critical review of the recent development of protease chemical probes which are small molecules that detect proteolytic activity by interacting with protease active site, individual proteases as well as complex proteolytic networks.

Abstract
A connection of a functional peptide with a cell-penetrating peptide (CPP) used a heterodimeric coiled-coil as a molecular zipper can improve the intracellular delivery and activity of the functional peptide. However, the chain length of the coiled coil required for functioning as the molecular zipper is unknown at present. To solve the problem, we prepared an autophagy-inducing peptide (AIP) that conjugates with the CPP via heterodimeric coiled-coils consisting of 1 to 4 repeating units (K/E zipper; AIP-Kn and En-CPP), and we investigated the optimum length of the K/E zipper for effective intracellular delivery and autophagy induction. Fluorescence spectroscopy showed that K/E zippers with n = 3 and 4 formed a stable 1:1 hybrid (AIP-K3/E3-CPP and AIP-K4/E4-CPP, respectively). Both AIP-K3 and AIP-K4 were successfully delivered into cells by the corresponding hybrid formation with K3-CPP and K4-CPP, respectively. Interestingly, autophagy was also induced by the K/E zippers with n = 3 and 4, more intensively by the former than by the latter. The peptides and K/E zippers used in this study did not show significant cytotoxicity. These results indicate that the effective induction of autophagy occurs via an exquisite balance of the association and dissociation of the K/E zipper in this system.

Abstract
We introduce a versatile strategy for the bioreversible modification of proteins. Our strategy is based on a tricomponent molecule, synthesized in three steps, that incorporates a diazo moiety for chemoselective esterification of carboxyl groups, a pyridyl disulfide group for late-stage functionalization with thiolated ligands, and a self-immolative carbonate group for esterase-mediated cleavage. Using cytochrome c (Cyt c) and the green fluorescent protein (GFP) as models, we generated protein conjugates modified with diverse domains for cellular delivery that include a small molecule, targeting and cell-penetrating peptides (CPPs), and a large polysaccharide. As a proof of concept, we used our strategy to effect the delivery of proteins into the cytosol of live mammalian cells in the presence of serum. The cellular delivery of functional Cyt c, which induces apoptosis, highlighted the advantage of bioreversible conjugation on a carboxyl group versus irreversible conjugation on an amino group. The ease and utility of this traceless modification provide new opportunities for chemical biologists.

Abstract
Deubiquitinating enzyme (DUB) abnormalities are associated with many diseases. Previous attempts have been made to introduce various chemical groups such as alkynes, unsaturated olefins and alkyl halides to the C-terminus of ubiquitin (Ub) to capture the active-site cysteine residue in DUBs for structural and biochemical studies. Here, we find that a Ub C-terminal acyl azide can capture DUBs, thereby forming thioester bonds in buffers and cell lysates. This finding not only makes ubiquitin acyl azide a chemical probe for capturing DUBs, but also extends the utility of azide groups in biological applications.

Abstract
Post-translational modification of proteins by Ubiquitin (Ub) and Ubiquitin-like proteins (Ubls) can be reversed by deconjugating enzymes, which have been implicated in different pathways and associated with various human diseases. To understand the activity and dynamics of deconjugating enzymes, multiple synthetic and semi-synthetic Ub/Ubl probes have been developed, and some of them have been applied to screen inhibitors of deconjugating enzymes. Since these Ub/Ubl probes are generally not cell-permeable, different strategies have been developed to deliver Ub/Ubl probes to live cells. However, till now, no Ub/Ubl probes can be expressed in live cells to directly report on the activities of deconjugating enzymes in the most relevant cellular environment. Here, we genetically encoded cross-linkable Ub/Ubl probes in live E. coli and HEK293T cells. These probes can cross-link with deconjugating enzymes in vitro and in vivo. Using these Ub probes combined with mass spectrometry, we have successfully identified endogenous deconjugating enzymes in live cells. We believe that these genetically encoded Ub/Ubl probes are valuable for investigating biological functions of deconjugating enzymes in physiological environments.

Abstract
Fluorescently tagged molecular probes capable of time- and concentration-dependent quantification of deubiquitinating enzyme (DUB) activity allow for precise characterization of both enzyme and DUB inhibitor. These probes are compatible with most plate readers allowing for rapid, facile fluorometric analysis of DUB activity. DUB activity can be measured in purified enzyme reactions, in cell lysates, or in intact cells depending upon the choice of the fluorometric probe. This chapter describes protocols and potential analysis tools to investigate DUB activity in these three scenarios.

Abstract
Ubiquitin and related ubiquitin-like proteins (Ubls) influence a variety of cellular pathways including protein degradation and response to viral infections. The chemical interrogation of these complex enzymatic cascades relies on the use of tailored activity-based probes (ABPs). Herein, we report the preparation of ABPs for ubiquitin, NEDD8, SUMO2 and ISG15 by selective acyl hydrazide modification. Acyl hydrazides of Ubls are readily accessible by direct hydrazinolysis of Ubl-intein fusions. The suppressed pK a and superior nucleophilicity of the acyl hydrazides enables their selective modification at acidic pH with carboxylic acid anhydrides. The modification proceeds rapidly and efficiently, and does not require chromatographic purification or refolding of the probes. We modified Ubl-NHNH2 with various thiol-reactive electrophiles that couple selectively with E2s and DUBs. The ease of modification enables the rapid generation and screening of ubiquitin probes with various C-terminal truncations and warheads for the selection of the most suitable combination for a given E2 or DUB.

Abstract
The reversible attachment of ubiquitin (Ub) and ubiquitin like modifiers (Ubls) to proteins are crucial post-translational modifications (PTMs) for many cellular processes. Not only do cells possess hundreds of ligases to mediate substrate specific modification with Ub and Ubls, but they also have a repertoire of more than 100 dedicated enzymes for the specific removal of ubiquitin (Deubiquitinases or DUBs) and Ubl modifications (Ubl-specific proteases or ULPs). Over the past two decades, there has been significant progress in our understanding of how DUBs and ULPs function at a molecular level and many novel DUBs and ULPs, including several new DUB classes, have been identified. Here, the development of chemical tools that can bind and trap active DUBs has played a key role. Since the introduction of the first activity-based probe for DUBs in 1986, several innovations have led to the development of more sophisticated tools to study DUBs and ULPs. In this review we discuss how chemical biology has led to the development of activity-based probes and substrates that have been invaluable to the study of DUBs and ULPs. We summarise our currently available toolbox, highlight the main achievements and give an outlook of how these tools may be applied to gain a better understanding of the regulatory mechanisms of DUBs and ULPs.

Abstract
Modifying cyclic cell-penetrating deca-arginine (cR10) peptides with 4-(4-dimethylaminophenylazo)benzoic acid (DABCYL) improves the uptake efficiency of synthetic ubiquitin (Ub) cargoes into living cells. To probe the role of the DABCYL moiety, we performed time-lapse microscopy and fluorescence lifetime imaging microscopy (FLIM) of fluorescent DABCYL-R10 to evaluate the impact on cell entry by the formation of nucleation zones. Furthermore, we performed a structure-uptake relationship study with 13 DABCYL derivatives coupled to CPP to examine their effect on the cell-uptake efficiency when conjugated to mono-Ub through disulfide linkages. Our results show that through structure variations of the DABCYL moiety alone we could reach, at nanomolar concentration, an additional threefold increase in the cytosolic delivery of Ub, which will enable studies on various intracellular processes related to Ub signaling.

On the Study of Deubiquitinases: Using the Right Tools for the Job. Biomolecules 2022; 12:biom12050703. [PMID: 35625630 PMCID: PMC9139131 DOI: 10.3390/biom12050703] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2022] [Revised: 05/05/2022] [Accepted: 05/12/2022] [Indexed: 02/01/2023] Open
Abstract
Deubiquitinases (DUBs) have been the subject of intense scrutiny in recent years. Many of their diverse enzymatic mechanisms are well characterized in vitro; however, our understanding of these enzymes at the cellular level lags due to the lack of quality tool reagents. DUBs play a role in seemingly every biological process and are central to many human pathologies, thus rendering them very desirable and challenging therapeutic targets. This review aims to provide researchers entering the field of ubiquitination with knowledge of the pharmacological modulators and tool molecules available to study DUBs. A focus is placed on small molecule inhibitors, ubiquitin variants (UbVs), and activity-based probes (ABPs). Leveraging these tools to uncover DUB biology at the cellular level is of particular importance and may lead to significant breakthroughs. Despite significant drug discovery efforts, only approximately 15 chemical probe-quality small molecule inhibitors have been reported, hitting just 6 of about 100 DUB targets. UbV technology is a promising approach to rapidly expand the library of known DUB inhibitors and may be used as a combinatorial platform for structure-guided drug design.

Abstract
There is currently a lack of reliable methods and strategies to probe the deubiquitinating enzyme UCHL3. Current small molecules reported for this purpose display reduced potency and selectivity in cellular assays. To bridge this gap and provide an alternative approach to probe UCHL3, our group has carried out the rational design of ubiquitin-variant activity-based probes with selectivity for UCHL3 over the closely related UCHL1 and other DUBs. The approach successfully produced a triple-mutant ubiquitin variant activity-based probe, UbVQ40V/T66K/V70F-PRG, that was ultimately 20,000-fold more selective for UCHL3 over UCHL1 when assessed by rate of inactivation assays. This same variant was shown to selectively form covalent adducts with UCHL3 in MDA-MB-231 breast cancer cells and no reactivity toward other DUBs expressed. Overall, this study demonstrates the feasibility of the approach and also provides insight into how this approach may be applied to other DUB targets.

Abstract
Protein-based therapeutics represent a rapidly growing segment of approved disease treatments. Successful intracellular delivery of proteins is an important precondition for expanded in vivo and in vitro applications of protein therapeutics. Direct modification of proteins and peptides for improved cytosolic translocation are a promising method of increasing delivery efficiency and expanding the viability of intracellular protein therapeutics. In this Review, we present recent advances in both synthetic and genetic protein modifications for intracellular delivery. Active endocytosis-based and passive internalization pathways are discussed, followed by a review of modification methods for improved cytosolic delivery. After establishing how proteins can be modified, general strategies for facilitating intracellular delivery, such as chemical supercharging or inclusion of cell-penetrating motifs, are covered. We then outline protein modifications that promote endosomal escape. We finally examine the delivery of two potential classes of therapeutic proteins, antibodies and associated antibody fragments, and gene editing proteins, such as cas9.

Abstract
Cell-penetrating peptides (CPPs) are versatile tools to deliver various molecules into different cell types. The majority of CPPs are usually represented by linear structures, but numerous recent studies demonstrated cyclization to be an effective strategy leading to favorable biological activities. Here we describe two different methods for the side chain and backbone cyclization of CPPs . Furthermore, we highlight straightforward procedures for the covalent coupling of fluorophores or cytotoxic payloads.

Abstract
Protein post-translational modifications are involved in essentially all aspects of cellular signaling. Their dynamic nature and the difficulties in installing them using enzymatic approaches limits their direct study in human cells. Reported herein is the first synthesis, delivery and cellular study of a stable phosphoubiquitin probe. Our results compare Parkin's substrate preference during mitophagy via direct visualization of a phosphorylated ubiquitin probe in the cellular environment.

Abstract
Post-translational modification of proteins by ubiquitin is required for nearly all aspects of eukaryotic cell function. The numerous targets of ubiquitylation, and variety of ubiquitin modifications, are often likened to a code, where the ultimate messages are diverse responses to target ubiquitylation. E1, E2, and E3 multiprotein enzymatic assemblies modify specific targets and thus function as messengers. Recent advances in chemical and protein tools have revolutionized our ability to explore the ubiquitin system, through enabling new high-throughput screening methods, matching ubiquitylation enzymes with their cellular targets, revealing intricate allosteric mechanisms regulating ubiquitylating enzymes, facilitating structural revelation of transient assemblies determined by multivalent interactions, and providing new paradigms for inhibiting and redirecting ubiquitylation in vivo as new therapeutics. Here we discuss the development of methods that control, disrupt, and extract the flow of information across the ubiquitin system and have enabled elucidation of the underlying molecular and cellular biology.

Abstract
Activity-based protein profiling (ABPP) is a technique that uses highly selective active-site targeted chemical probes to label and monitor the state of proteins. ABPP integrates the strengths of both chemical and biological disciplines. By utilizing chemically synthesized or modified bioactive molecules, ABPP is able to reveal complex physiological and pathological enzyme-substrate interactions at molecular and cellular levels. It is also able to provide critical information of the catalytic activity changes of enzymes, annotate new functions of enzymes, discover new substrates of enzymes, and allow real-time monitoring of the cellular location of enzymes. Based on the mechanism of probe-enzyme interaction, two types of probes that have been used in ABPP are activity-based probes (ABPs) and affinity-based probes (AfBPs). This review highlights the recent advances in the use of ABPs and AfBPs, and summarizes their design strategies (based on inhibitors and substrates) and detection approaches.

Abstract
Ubiquitination is an important protein post-translational modification regulating many cellular processes in eukaryotes. Ubiquitination is catalyzed by a three-enzyme cascade resulting in the conjugation of the C-terminal carboxylate of ubiquitin (Ub) to the ε-amino group of a lysine residue in the acceptor protein via an isopeptide bond. In vitro enzymatic ubiquitination utilizing Ub ligases has been successfully employed to generate Ub dimers and polymers. However, limitations of the enzymatic approach exist, particularly due to the requirement of specific Ub ligase for any given target protein and the low catalytic efficiency of the Ub ligase. To achieve an in-depth understanding of the molecular mechanism of Ub signaling, new methods are needed to generate mono- and poly-ubiquitinated proteins at a specific site with defined polyubiquitin chain linkage and length. Chemical methods offer an attractive solution to the above-described challenges. In this review, we summarize the recently developed chemical methods for generating ubiquitinated proteins using synthetic and semisynthetic approaches. These new tools and approaches, as an important part of the Ub toolbox, are crucial to our understanding and exploitation of the Ub system for novel therapeutics.

Abstract
Live-cell delivery of a fully synthetic protein having selectivity towards a particular target is a promising approach with potential applications for basic research and therapeutics. Cell-penetrating peptides (CPPs) allow the cellular delivery of proteins but mostly result in endosomal entrapment, leading to lack of bioavailability. Herein, we report the design and synthesis of a CPP fused to 4-((4-(dimethylamino)phenyl)azo)benzoic acid (DABCYL) to enhance cellular uptake of fluorescently labelled synthetic protein analogues in low micromolar concentration. The attachment of cyclic deca-arginine (cR10) modified with a single lysine linked to DABCYL to synthetic ubiquitin (Ub) and small ubiquitin-like modifier-2 (SUMO-2) scaffolds resulted in a threefold higher uptake efficacy in live cells compared to the unmodified cR10. We could also achieve cR10DABCYL-assisted delivery of Ub and a Ub variant (Ubv) based activity-based probes for functional studies of deubiquitinases in live cells.

Abstract
Eosin Y was assessed for its ability to induce a thiol-ene dependent protein-protein reaction in a metal-free, oxygen-tolerant, visible light mediated system. Protein-protein coupling efficiency under these mild conditions was comparable to previously reported UV-dependent conditions. The desired thiol-ene reaction was however limited within more complex biological systems.

Abstract
A heterodimeric leucine zipper composed of a pair of leucine zipper peptides containing acidic or basic amino acid residues at appropriate positions in each peptide was used as a molecular glue to connect protein cargos to a cell-penetrating peptide (CPP) carrier. To investigate the hybridization properties by fluorescence experiments, we prepared an enhanced green fluorescent protein (EGFP) fused with an acidic leucine zipper (LzK), EGFP-LzK, and a basic leucine zipper (LzE) modified with a CPP, LzE-CPP. The LzK and LzE formed a 1:1 hybrid when EGFP-LzK and LzE-CPP were mixed in phosphate buffer saline, thereby conjugating the EGFP with the CPP. The formation of the 1:1 hybrid was confirmed by fluorescence spectra and fluorescence titration curves. Results from fluorescence microscopy experiments showed that EGFP was successfully delivered into cells by conjugating with the CPP via formation of the LzK/LzE hybrid. We also fused the apoptotic protein p53 with LzK (p53-LzK) and investigated the inhibition of cell proliferation of various cell lines by incubation with the p53-LzK/LzE-CPP hybrid. This hybrid was found to localize in nuclei and successfully inhibited cell-specific proliferation. The LzE/LzK zipper system inhibited cell proliferation more efficiently than the directly fused conjugate, p53-CPP. Our method will be a useful drug delivery system for delivering bioactive proteins to treat various diseases.

Abstract
Photocaged cell-permeable ubiquitin probe holds promise in profiling the activity of cellular deubiquitinating enzymes (DUBs) with the much needed temporal control. Here we report a new photocaged cell-permeable ubiquitin probe that undergoes photoactivation upon 365 nm UV treatment and enables intracellular deubiquitinating enzyme profiling. We used a semisynthetic approach to generate modular ubiquitin-based probe containing a tetrazole-derived warhead at the C-terminus of ubiquitin and employed a cyclic polyarginine cell-penetrating peptide (cR10) conjugated to the N-terminus of ubiquitin via a disulfide linkage to deliver the probe into live cells. Upon 365 nm UV irradiation, the tetrazole group is converted to a nitrilimine intermediate in situ, which reacts with nearby nucleophilic cysteine residue from the DUB active site. The new photocaged cell-permeable probe showed good reactivity toward purified DUBs, including USP2, UCHL1, and UCHL3, upon photoirradiation. The Ub-tetrazole probe was also assessed in HeLa cell lysate and showed robust labeling only upon photoactivation. We further carried out protein profiling in intact HeLa cells using the new photocaged cell-permeable ubiquitin probe and identified DUBs captured by the probe using label-free quantitative (LFQ) mass spectrometry. Importantly, the photocaged cell-permeable ubiquitin probe captured DUBs specifically in respective G1/S and G2/M phases in synchronized HeLa cells. Moreover, using this probe DUBs were profiled at different time points following the release of HeLa cells from G1/S phase. Our results showed that photocaged cell-permeable probe represents a valuable new tool for achieving a better understanding of the cellular functions of DUBs.

Abstract
About 70% of the drugs in use are derived from natural products, either used directly or in chemically modified form. Among all possible small molecules (not greater than 5 kDa), only a few of them are biologically active. Natural product libraries may have a higher rate of finding "hits" than synthetic libraries, even with the use of fewer compounds. This is due to the complementarity between the "chemical space" of small molecules and biological macromolecules such as proteins, DNA and RNA, in addition to the three-dimensional complexity of NPs. Chemical probes are molecules which aid in the elucidation of the biological mechanisms behind the action of drugs or drug-like molecules by binding with macromolecular/cellular interaction partners. Probe development and application have been spurred by advancements in photoaffinity label synthesis, affinity chromatography, activity based protein profiling (ABPP) and instrumental methods such as cellular thermal shift assay (CETSA) and advanced/hyphenated mass spectrometry (MS) techniques, as well as genome sequencing and bioengineering technologies. In this review, we restrict ourselves to a survey of natural products (including peptides/mini-proteins and excluding antibodies), which have been applied largely in the last 5 years for the target identification of drugs/drug-like molecules used in research on infectious diseases, and the description of their mechanisms of action.

Abstract
![]()
Many reagents have emerged to study
the function of specific enzymes in vitro. On the
other hand, target specific reagents are
scarce or need improvement, allowing investigations of the function
of individual enzymes in their native cellular context. Here we report
the development of a target-selective fluorescent small-molecule activity-based
DUB probe that is active in live cells and an in vivo animal model. The probe labels active ubiquitin carboxy-terminal
hydrolase L1 (UCHL1), also known as neuron-specific protein PGP9.5
(PGP9.5) and Parkinson disease 5 (PARK5), a DUB active in neurons
that constitutes 1 to 2% of the total brain protein. UCHL1 variants
have been linked with neurodegenerative disorders Parkinson’s
and Alzheimer’s diseases. In addition, high levels of UCHL1
also correlate often with cancer and especially metastasis. The function
of UCHL1 activity or its role in cancer and neurodegenerative disease
is poorly understood and few UCHL1-specific activity tools exist.
We show that the reagents reported here are specific to UCHL1 over
all other DUBs detectable by competitive activity-based protein profiling
and by mass spectrometry. Our cell-penetrable probe, which contains
a cyanimide reactive moiety, binds to the active-site cysteine residue
of UCHL1 in an activity-dependent manner. Its use is demonstrated
by the fluorescent labeling of active UCHL1 both in vitro and in live cells. We furthermore show that this probe can selectively
and spatiotemporally report UCHL1 activity during the development
of zebrafish embryos. Our results indicate that our probe has potential
applications as a diagnostic tool for diseases with perturbed UCHL1
activity.

Abstract
Deubiquitinating enzymes regulate various cellular processes, particularly protein degradation, localization, and protein-protein interactions. The dysregulation of deubiquitinating enzyme (DUB) activity has been linked to several diseases; however, the function of many DUBs has not been identified. Therefore, the development of methods to assess DUB activity is important to identify novel DUBs, characterize DUB selectivity, and profile dynamic DUB substrates. Here, we review various methods of evaluating DUB activity using cell lysates or purified DUBs, as well as the types of probes used in these methods. In addition, we introduce some techniques that can deliver DUB probes into the cells and cell-permeable activity-based probes to directly visualize and quantify DUB activity in live cells. This review could contribute to the development of DUB inhibitors by providing important information on the characteristics and applications of various probes used to evaluate and detect DUB activity in vitro and in vivo.

Abstract
Activity-based protein profiling (ABPP) is recognized as a powerful and versatile chemoproteomic technology in drug discovery. Central to ABPP is the use of activity-based probes to report the activity of specific enzymes or reactivity of amino acid types in complex biological systems. Over the last two decades, ABPP has facilitated the identification of new drug targets and discovery of lead compounds in human and infectious disease. Furthermore, as part of a sustained global effort to illuminate the druggable proteome, the repertoire of target classes addressable with activity-based probes has vastly expanded in recent years. Here, we provide an overview of ABPP and summarise the major technological advances with an emphasis on probe development.

Abstract
Protein ubiquitination regulates almost every process in eukaryotic cells. The study of the many enzymes involved in the ubiquitination system and the development of ubiquitination-associated therapeutics are important areas of current research. Synthetic tools such as ubiquitin-based chemical probes have been making an increasing contribution to deciphering various biochemical components involved in ubiquitin conjugation, recruitment, signaling, and deconjugation. In the present minireview, we summarize the progress of ubiquitin-based chemical probes with an emphasis on their various structures and chemical synthesis. We discuss the utility of the ubiquitin-based chemical probes for discovering and profiling ubiquitin-dependent signaling systems, as well as the monitoring and visualization of ubiquitin-related enzymatic machinery. We also show how the probes can serve to elucidate the molecular mechanism of recognition and catalysis. Collectively, the development and application of ubiquitin-based chemical probes emphasizes the importance and utility of chemical protein synthesis in modern chemical biology. This article reviews the design, synthesis, and application of different classes of Ub-based chemical probes.![]()

Abstract
Ubiquitin chains with distinct topologies play essential roles in eukaryotic cells. Recently, it was discovered that multiple ubiquitin units can be ligated to more than one lysine residue in the same ubiquitin to form diverse branched ubiquitin chains. Although there is increasing evidence implicating these branched chains in a plethora of biological functions, few mechanistic details have been elucidated. This concept article introduces the function, detection and chemical synthesis of branched ubiquitin chains; and offers some future perspective for this exciting new field.

Abstract
Deubiquitinating enzymes (DUBs) are known to have numerous important interactions with the ubiquitin cascade and their dysregulation is associated with several diseases, including cancer and neurodegeneration. They are an important class of enzyme, and activity-based probes have been developed as an effective strategy to study them. Existing activity-based probes that target the active site of these enzymes work via nucleophilic mechanisms. We present the development of latent ubiquitin-based probes that target DUBs via a site selective, photoinitiated radical mechanism. This approach differs from existing photocrosslinking probes as it requires a free active site cysteine. In contrast to existing cysteine reactive probes, control over the timing of the enzyme-probe reaction is possible as the alkene warhead is completely inert under ambient conditions, even upon probe binding. The probe's reactivity has been demonstrated against recombinant DUBs and to capture endogenous DUB activity in cell lysate. This allows more finely resolved investigations of DUBs.

Abstract
The regulation of ubiquitination status in the cell is controlled by ubiquitin ligases acting in tandem with deubiquitinating enzymes. Ubiquitination controls many key processes in the cell from division to death making its tight regulation key to optimal cell function. Activity based protein profiling has emerged as a powerful technique to study these important enzymes. With around 100 deubiquitinating enzymes and 600 ubiquitin ligases in the human genome targeting a subclass of these enzymes or even a single enzyme is a compelling strategy to unpick this complex system. In this review we will discuss different approaches adopted, including activity-based probes centered around ubiquitin-protein, ubiquitin-peptide and mutated ubiquitin scaffolds. We examine challenges faced and opportunities presented to increase specificity in activity-based protein profiling of the ubiquitin conjugation/deconjugation machinery.

Abstract
Ubiquitination is emerging as an important post-translational modification (PTM) for numerous cellular functions including protein degradation, DNA damage repair and tolerance, and cell cycle progression. Compared with other small-molecule modifiers found in phosphorylation, acetylation and glycosylation, ubiquitin is a small protein modifier that exists as either a single ubiquitin or a polyubiquitin chain. Furthermore, the polyubiquitin chains are formed via various linkages imparting an additional layer of specificity in cellular signaling. In order to adequately study ubiquitin signaling and particularly deubiquitination, a number of ubiquitin activity-based probes (ABPs) were developed and utilized in understanding the deubiquitinase (DUBs) function. Here, we focus on the current state of the DUB ABP development and their application in understanding DUB function and specificity for polyubiquitin chains and ubiquitinated proteins.

Abstract
Deubiquitinating enzymes (DUBs) function to remove or cleave ubiquitin from post-translationally modified protein substrates. There are about 100 known DUBs in the proteome, and their dysregulation has been implicated a number of disease states, but the specific function of many subclass members remains poorly understood. Activity-based probes (ABPs) react covalently with an active site residue to report on specific enzyme activity, and thus represent a powerful method to evaluate cellular and physiological enzyme function and dynamics. Ubiquitin-based ABPs, such as HA-Ub-VME, an epitope-tagged ubiquitin carrying a C-terminal reactive warhead, are the leading tool for "DUBome" activity profiling. However, these probes are generally cell membrane impermeable, limiting their use to isolated enzymes or lysates. Development of cell-permeable ABPs would allow engagement of DUB enzymes directly within the context of an intact live cell or organism, refining our understanding of physiological and pathological function, and greatly enhancing opportunities for translational research, including target engagement, imaging and biomarker discovery. This mini-review discusses recent developments in small molecule activity-based probes that target DUBs in live cells, and the unique applications of cell-permeable DUB activity-based probes vs. their traditional ubiquitin-based counterparts.
