Abstract
Long-term perturbation of de novo chromatin assembly during DNA replication has profound effects on epigenome maintenance and cell fate. The early mechanistic origin of these defects is unknown. Here, we combine acute degradation of Chromatin Assembly Factor 1 (CAF-1), a key player in de novo chromatin assembly, with single-cell genomics, quantitative proteomics, and live-microscopy to uncover these initiating mechanisms in human cells. CAF-1 loss immediately slows down DNA replication speed and renders nascent DNA hyperaccessible. A rapid cellular response, distinct from canonical DNA damage signaling, is triggered and lowers histone mRNAs. As a result, histone variants usage and their modifications are altered, limiting transcriptional fidelity and delaying chromatin maturation within a single S-phase. This multi-level response induces a cell-cycle arrest after mitosis. Our work reveals the immediate consequences of defective de novo chromatin assembly during DNA replication, explaining how at later times the epigenome and cell fate can be altered.

Abstract
All vertebrate genomes encode for three large histone H2A variants that have an additional metabolite-binding globular macrodomain module, macroH2A. MacroH2A variants impact heterochromatin organization and transcription regulation and establish a barrier for cellular reprogramming. However, the mechanisms of how macroH2A is incorporated into chromatin and the identity of any chaperones required for histone deposition remain elusive. Here, we develop a split-GFP-based assay for chromatin incorporation and use it to conduct a genome-wide mutagenesis screen in haploid human cells to identify proteins that regulate macroH2A dynamics. We show that the histone chaperone ANP32B is a regulator of macroH2A deposition. ANP32B associates with macroH2A in cells and in vitro binds to histones with low nanomolar affinity. In vitro nucleosome assembly assays show that ANP32B stimulates deposition of macroH2A-H2B and not of H2A-H2B onto tetrasomes. In cells, depletion of ANP32B strongly affects global macroH2A chromatin incorporation, revealing ANP32B as a macroH2A histone chaperone.

Abstract
During every cell cycle, both the genome and the associated chromatin must be accurately replicated. Chromatin Assembly Factor-1 (CAF-1) is a key regulator of chromatin replication, but how CAF-1 functions in relation to the DNA replication machinery is unknown. Here, we reveal that this crosstalk differs between the leading and lagging strand at replication forks. Using biochemical reconstitutions, we show that DNA and histones promote CAF-1 recruitment to its binding partner PCNA and reveal that two CAF-1 complexes are required for efficient nucleosome assembly under these conditions. Remarkably, in the context of the replisome, CAF-1 competes with the leading strand DNA polymerase epsilon (Polϵ) for PCNA binding. However, CAF-1 does not affect the activity of the lagging strand DNA polymerase Delta (Polδ). Yet, in cells, CAF-1 deposits newly synthesized histones equally on both daughter strands. Thus, on the leading strand, chromatin assembly by CAF-1 cannot occur simultaneously to DNA synthesis, while on the lagging strand these processes may be coupled. We propose that these differences may facilitate distinct parental histone recycling mechanisms and accommodate the inherent asymmetry of DNA replication.

Abstract
Nucleosome assembly requires the coordinated deposition of histone complexes H3-H4 and H2A-H2B to form a histone octamer on DNA. In the current paradigm, specific histone chaperones guide the deposition of first H3-H4 and then H2A-H2B. Here, we show that the acidic domain of DNA repair factor APLF (APLFAD) can assemble the histone octamer in a single step and deposit it on DNA to form nucleosomes. The crystal structure of the APLFAD-histone octamer complex shows that APLFAD tethers the histones in their nucleosomal conformation. Mutations of key aromatic anchor residues in APLFAD affect chaperone activity in vitro and in cells. Together, we propose that chaperoning of the histone octamer is a mechanism for histone chaperone function at sites where chromatin is temporarily disrupted.

Abstract
Eukaryotic chromatin is a highly dynamic structure with essential roles in virtually all DNA-dependent cellular processes. Nucleosomes are a barrier to DNA access, and during DNA replication, they are disassembled ahead of the replication machinery (the replisome) and reassembled following its passage. The Histone chaperone Chromatin Assembly Factor-1 (CAF-1) interacts with the replisome and deposits H3-H4 directly onto newly synthesized DNA. Therefore, CAF-1 is important for the establishment and propagation of chromatin structure. The molecular mechanism by which CAF-1 mediates H3-H4 deposition has remained unclear. However, recent studies have revealed new insights into the architecture and stoichiometry of the trimeric CAF-1 complex and how it interacts with and deposits H3-H4 onto substrate DNA. The CAF-1 trimer binds to a single H3-H4 dimer, which induces a conformational rearrangement in CAF-1 promoting its interaction with substrate DNA. Two CAF-1•H3-H4 complexes co-associate on nucleosome-free DNA depositing (H3-H4)2 tetramers in the first step of nucleosome assembly. Here, we review the progress made in our understanding of CAF-1 structure, mechanism of action, and how CAF-1 contributes to chromatin dynamics during DNA replication.

Abstract
How did the nucleosome, the fundamental building block of all eukaryotic chromatin, evolve? This central question has been impossible to address because the four core histones that make up the protein core of the nucleosome are so highly conserved in all eukaryotes. With the discovery of small, minimalist histone-like proteins in most known archaea, the likely origin of histones was identified. We recently determined the structure of an archaeal histone-DNA complex, revealing that archaeal DNA topology and protein-DNA interactions are astonishingly similar compared to the eukaryotic nucleosome. This was surprising since most archaeal histones form homodimers which consist only of the minimal histone fold and are devoid of histone tails and extensions. Unlike eukaryotic H2A-H2B and H3-H4 heterodimers that assemble into octameric particles wrapping ~ 150 bp DNA, archaeal histones form polymers around which DNA coils in a quasi-continuous superhelix. At any given point, this superhelix has the same geometry as nucleosomal DNA. This suggests that the architectural role of histones (i.e. the ability to bend DNA into a nucleosomal superhelix) was established before archaea and eukaryotes diverged, while the ability to form discrete particles, together with signaling functions of eukaryotic chromatin (i.e. epigenetic modifications) were secondary additions.

Abstract
Nucleosomes organize the eukaryotic genome into chromatin. In cells, nucleosome assembly relies on the activity of histone chaperones, proteins with high binding affinity to histones. At least a subset of histone chaperones promotes histone deposition in vivo. However, it has been challenging to characterize this activity, due to the lack of quantitative assays. Here we developed a quantitative nucleosome assembly (NAQ) assay to measure the amount of nucleosome formation in vitro. This assay relies on a Micrococcal nuclease (MNase) digestion step that yields DNA fragments protected by the deposited histone proteins. A subsequent run on the Bioanalyzer machine allows the accurate quantification of the fragments (length and amount), relative to a loading control. This allows us to measure nucleosome formation by following the signature DNA length of ~150 bp. This assay finally enables the characterization of the nucleosome assembly activity of different histone chaperones, a step forward in the understanding of the functional roles of these proteins in vivo.

Abstract
For a complete understanding of biochemical reactions, information on complex stoichiometry is essential. However, measuring stoichiometry is experimentally challenging. Our lab has developed a FRET-based assay to study protein complex stoichiometry in vitro. This assay, also known as Job plot, is set up as a continuous variation of the molar ratio between the two species, kept at constant total concentration. The FRET (Fluorescence Resonance Energy Transfer) between the two fluorescently-labeled proteins is measured and the stoichiometry is inferred from the sample with highest FRET signal. This approach allows us to assess complex stoichiometry in solution.

Abstract
Small basic proteins present in most Archaea share a common ancestor with the eukaryotic core histones. We report the crystal structure of an archaeal histone-DNA complex. DNA wraps around an extended polymer, formed by archaeal histone homodimers, in a quasi-continuous superhelix with the same geometry as DNA in the eukaryotic nucleosome. Substitutions of a conserved glycine at the interface of adjacent protein layers destabilize archaeal chromatin, reduce growth rate, and impair transcription regulation, confirming the biological importance of the polymeric structure. Our data establish that the histone-based mechanism of DNA compaction predates the nucleosome, illuminating the origin of the nucleosome.

Abstract
Nucleosome assembly in the wake of DNA replication is a key process that regulates cell identity and survival. Chromatin assembly factor 1 (CAF-1) is a H3-H4 histone chaperone that associates with the replisome and orchestrates chromatin assembly following DNA synthesis. Little is known about the mechanism and structure of this key complex. Here we investigate the CAF-1•H3-H4 binding mode and the mechanism of nucleosome assembly. We show that yeast CAF-1 binding to a H3-H4 dimer activates the Cac1 winged helix domain interaction with DNA. This drives the formation of a transient CAF-1•histone•DNA intermediate containing two CAF-1 complexes, each associated with one H3-H4 dimer. Here, the (H3-H4)2 tetramer is formed and deposited onto DNA. Our work elucidates the molecular mechanism for histone deposition by CAF-1, a reaction that has remained elusive for other histone chaperones, and it advances our understanding of how nucleosomes and their epigenetic information are maintained through DNA replication.

Abstract
Chromatin accessibility is modulated by structural transitions that provide timely access to the genetic and epigenetic information during many essential nuclear processes. These transitions are orchestrated by regulatory proteins that coordinate intricate structural modifications and signaling pathways. In vitro reconstituted chromatin samples from defined components are instrumental in defining the mechanistic details of such processes. The bottleneck to appropriate in vitro analysis is the production of high quality, and quality-controlled, chromatin substrates. In this chapter, we describe methods for in vitro chromatin reconstitution and quality control. We highlight the strengths and weaknesses of various approaches and emphasize quality control steps that ensure reconstitution of a bona fide homogenous chromatin preparation. This is essential for optimal reproducibility and reliability of ensuing experiments using chromatin substrates.

Abstract
During DNA damage response, the RING E3 ligase RNF168 ubiquitinates nucleosomal H2A at K13–15. Here we show that the ubiquitination reaction is regulated by its substrate. We define a region on the RING domain important for target recognition and identify the H2A/H2B dimer as the minimal substrate to confer lysine specificity to the RNF168 reaction. Importantly, we find an active role for the substrate in the reaction. H2A/H2B dimers and nucleosomes enhance the E3-mediated discharge of ubiquitin from the E2 and redirect the reaction towards the relevant target, in a process that depends on an intact acidic patch. This active contribution of a region distal from the target lysine provides regulation of the specific K13–15 ubiquitination reaction during the complex signalling process at DNA damage sites. The E3 ubiquitin ligase RNF168 ubiquitinates specific lysines on histone H2A as part of the DNA damage response. Here, the authors show that the acidic patch on the histone H2A/H2B dimer catalyses RNF168-dependent ubiquitination of histone 2A by redirecting ubiquitination activity towards the relevant target lysines.

Abstract
Histone proteins dynamically regulate chromatin structure and epigenetic signaling to maintain cell homeostasis. These processes require controlled spatial and temporal deposition and eviction of histones by their dedicated chaperones. With the evolution of histone variants, a network of functionally specific histone chaperones has emerged. Molecular details of the determinants of chaperone specificity for different histone variants are only slowly being resolved. A complete understanding of these processes is essential to shed light on the genuine biological roles of histone variants, their chaperones, and their impact on chromatin dynamics.

Abstract
Ubiquitin and ubiquitin-like modifications are central to virtually all cellular signaling pathways. They occur primarily on lysine residues of target proteins and stimulate a large number of downstream signals. The diversity of these signals depends on the type, location and dynamics of the modification, but the role of the exact site of modification and the selectivity for specific lysines are poorly understood. Here we review the current literature on lysine specificity in these modifications, and we highlight the known signaling mechanisms and the open questions that pose future challenges to ubiquitin research.

Abstract
Ubiquitin-dependent signaling during the DNA damage response (DDR) to double-strand breaks (DSBs) is initiated by two E3 ligases, RNF8 and RNF168, targeting histone H2A and H2AX. RNF8 is the first ligase recruited to the damage site, and RNF168 follows RNF8-dependent ubiquitination. This suggests that RNF8 initiates H2A/H2AX ubiquitination with K63-linked ubiquitin chains and RNF168 extends them. Here, we show that RNF8 is inactive toward nucleosomal H2A, whereas RNF168 catalyzes the monoubiquitination of the histones specifically on K13-15. Structure-based mutagenesis of RNF8 and RNF168 RING domains shows that a charged residue determines whether nucleosomal proteins are recognized. We find that K63 ubiquitin chains are conjugated to RNF168-dependent H2A/H2AX monoubiquitination at K13-15 and not on K118-119. Using a mutant of RNF168 unable to target histones but still catalyzing ubiquitin chains at DSBs, we show that ubiquitin chains per se are insufficient for signaling, but RNF168 target ubiquitination is required for DDR.

Abstract
Sumoylation affects many cellular processes by regulating the interactions of modified targets with downstream effectors. Here we identified the cytosolic dipeptidyl peptidase 9 (DPP9) as a SUMO1 interacting protein. Surprisingly, DPP9 binds to SUMO1 independent of the well known SUMO interacting motif, but instead interacts with a loop involving Glu(67) of SUMO1. Intriguingly, DPP9 selectively associates with SUMO1 and not SUMO2, due to a more positive charge in the SUMO1-loop. We mapped the SUMO-binding site of DPP9 to an extended arm structure, predicted to directly flank the substrate entry site. Importantly, whereas mutants in the SUMO1-binding arm are less active compared with wild-type DPP9, SUMO1 stimulates DPP9 activity. Consistent with this, silencing of SUMO1 leads to a reduced cytosolic prolyl-peptidase activity. Taken together, these results suggest that SUMO1, or more likely, a sumoylated protein, acts as an allosteric regulator of DPP9.

Abstract
Prostate cancer (PCa) is a major lethal malignancy in men, but the molecular events and their interplay underlying prostate carcinogenesis remain poorly understood. Epigenetic events and the upregulation of polycomb group silencing proteins including Bmi1 have been described to occur during PCa progression. Here, we found that conditional overexpression of Bmi1 in mice induced prostatic intraepithelial neoplasia, and elicited invasive adenocarcinoma when combined with PTEN haploinsufficiency. In addition, Bmi1 and the PI3K/Akt pathway were coactivated in a substantial fraction of human high-grade tumors. We found that Akt mediated Bmi1 phosphorylation, enhancing its oncogenic potential in an Ink4a/Arf-independent manner. This process also modulated the DNA damage response and affected genomic stability. Together, our findings demonstrate the etiological role of Bmi1 in PCa, unravel an oncogenic collaboration between Bmi1 and the PI3K/Akt pathway, and provide mechanistic insights into the modulation of Bmi1 function by phosphorylation during prostate carcinogenesis.

Abstract
In response to DNA damage, cells initiate complex signalling cascades leading to growth arrest and DNA repair. The recruitment of 53BP1 to damaged sites requires the activation of the ubiquitination cascade controlled by the E3 ubiquitin ligases RNF8 and RNF168, and methylation of histone H4 on lysine 20. However, molecular events that regulate the accessibility of methylated histones, to allow the recruitment of 53BP1 to DNA breaks, are unclear. Here, we show that like 53BP1, the JMJD2A (also known as KDM4A) tandem tudor domain binds dimethylated histone H4K20; however, JMJD2A is degraded by the proteasome following the DNA damage in an RNF8-dependent manner. We demonstrate that JMJD2A is ubiquitinated by RNF8 and RNF168. Moreover, ectopic expression of JMJD2A abrogates 53BP1 recruitment to DNA damage sites, indicating a role in antagonizing 53BP1 for methylated histone marks. The combined knockdown of JMJD2A and JMJD2B significantly rescued the ability of RNF8- and RNF168-deficient cells to form 53BP1 foci. We propose that the RNF8-dependent degradation of JMJD2A regulates DNA repair by controlling the recruitment of 53BP1 at DNA damage sites.

Abstract
Ether phospholipids are essential constituents of eukaryotic cell membranes. Rhizomelic chondrodysplasia punctata type 3 is a severe peroxisomal disorder caused by inborn deficiency of alkyldihydroxyacetonephosphate synthase (ADPS). The enzyme carries out the most characteristic step in ether phospholipid biosynthesis: formation of the ether bond. The crystal structure of ADPS from Dictyostelium discoideum shows a fatty-alcohol molecule bound in a narrow hydrophobic tunnel, specific for aliphatic chains of 16 carbons. Access to the tunnel is controlled by a flexible loop and a gating helix at the protein-membrane interface. Structural and mutagenesis investigations identify a cluster of hydrophilic catalytic residues, including an essential tyrosine, possibly involved in substrate proton abstraction, and the arginine that is mutated in ADPS-deficient patients. We propose that ether bond formation might be orchestrated through a covalent imine intermediate with the flavin, accounting for the noncanonical employment of a flavin cofactor in a nonredox reaction.

Abstract
Alkyldihydroxyacetonephosphate is the building block for the biosynthesis of ether phospholipids, which are essential components of eukaryotic cell membranes and are involved in a variety of signaling processes. The metabolite is synthesized by alkyldihydroxyacetonephosphate synthase (ADPS), a peroxisomal flavoenzyme. Deficiency in ADPS activity causes rhizomelic chondrodysplasia punctata type 3, a very severe genetic disease. ADPS is unusual in that it uses a typical redox cofactor such as FAD to catalyze a non-redox reaction. With the goal of undertaking a structural investigation of the enzyme, we have characterized recombinant ADPS from different sources: Cavia porcellus, Drosophila melanogaster, Homo sapiens, Archaeoglobus fulgidus, and Dictyostelium discoideum. The protein from D. discoideum was found to be the best candidate for structural studies. We describe a protocol for expression and purification of large amounts of pure and stable enzyme in its holo (FAD-bound) form. A search of deletion mutants identified a protein variant that forms crystals diffracting up to 2A resolution.
