Abstract
Mitochondrial and peroxisomal anchored protein ligase (MAPL) is a dual ubiquitin and small ubiquitin-like modifier (SUMO) ligase with roles in mitochondrial quality control, cell death and inflammation in cultured cells. Here, we show that MAPL function in the organismal context converges on metabolic control, as knockout mice are viable, insulin-sensitive, and protected from diet-induced obesity. MAPL loss leads to liver-specific activation of the integrated stress response, inducing secretion of stress hormone FGF21. MAPL knockout mice develop fully penetrant spontaneous hepatocellular carcinoma. Mechanistically, the peroxisomal bile acid transporter ABCD3 is a primary MAPL interacting partner and SUMOylated in a MAPL-dependent manner. MAPL knockout leads to increased bile acid production coupled with defective regulatory feedback in liver in vivo and in isolated primary hepatocytes, suggesting cell-autonomous function. Together, our findings establish MAPL function as a regulator of bile acid synthesis whose loss leads to the disruption of bile acid feedback mechanisms. The consequences of MAPL loss in liver, along with evidence of tumor suppression through regulation of cell survival pathways, ultimately lead to hepatocellular carcinogenesis.

Abstract
Chromatin structure, transcription, DNA replication, and repair are regulated via locus-specific incorporation of histone variants and posttranslational modifications that guide effector chromatin-binding proteins. Here we report unbiased, quantitative interactomes for the replication-coupled (H3.1) and replication-independent (H3.3) histone H3 variants based on BioID proximity labeling, which allows interactions in intact, living cells to be detected. Along with a significant proportion of previously reported interactions detected by affinity purification followed by mass spectrometry, three quarters of the 608 histone-associated proteins that we identified are new, uncharacterized histone associations. The data reveal important biological nuances not captured by traditional biochemical means. For example, we found that the chromatin assembly factor-1 histone chaperone not only deposits the replication-coupled H3.1 histone variant during S-phase but also associates with H3.3 throughout the cell cycle in vivo. We also identified other variant-specific associations, such as with transcription factors, chromatin regulators, and with the mitotic machinery. Our proximity-based analysis is thus a rich resource that extends the H3 interactome and reveals new sets of variant-specific associations.

Abstract
Rab11 GTPase proteins are required for cytokinesis, ciliogenesis, and lumenogenesis. Rab11a is critical for apical delivery of podocalyxin (PODXL) during lumen formation in epithelial cells. SH3BP5 and SH3BP5L are guanine nucleotide exchange factors (GEFs) for Rab11. We show that SH3BP5 and SH3BP5L are required for activation of Rab11a and cyst lumen formation. Using proximity-dependent biotin identification (BioID) interaction proteomics, we have identified SH3BP5 and its paralogue SH3BP5L as new substrates of the poly-ADP-ribose polymerase Tankyrase and the E3 ligase RNF146. We provide data demonstrating that epithelial polarity via cyst lumen formation is governed by Tankyrase, which inhibits Rab11a activation through the suppression of SH3BP5 and SH3BP5L. RNF146 reduces Tankyrase protein abundance and restores Rab11a activation and lumen formation. Thus, Rab11a activation is controlled by a signaling pathway composed of the sequential inhibition of SH3BP5 paralogues by Tankyrase, which is itself suppressed by RNF146.

Abstract
Cilia and flagella are microtubule-based cellular projections with important sensory and motility functions. Their absence or malfunction is associated with a growing number of human diseases collectively referred to as ciliopathies. However, the fundamental mechanisms underpinning cilia biogenesis and functions remain only partly understood. Here, we show that depleting LUZP1 or its interacting protein, EPLIN, increases the levels of MyosinVa at the centrosome and primary cilia formation. We further show that LUZP1 localizes to both actin filaments and the centrosome/basal body. Like EPLIN, LUZP1 is an actin-stabilizing protein that regulates actin dynamics, at least in part, by mobilizing ARP2 to the centrosomes. Both LUZP1 and EPLIN interact with known ciliogenesis and cilia-length regulators and as such represent novel players in actin-dependent centrosome to basal body conversion. Ciliogenesis deregulation caused by LUZP1 or EPLIN loss may thus contribute to the pathology of their associated disease states.

Abstract
The world is facing a global pandemic of COVID-19 caused by the SARS-CoV-2 coronavirus. Here we describe a collection of codon-optimized coding sequences for SARS-CoV-2 cloned into Gateway-compatible entry vectors, which enable rapid transfer into a variety of expression and tagging vectors. The collection is freely available. We hope that widespread availability of this SARS-CoV-2 resource will enable many subsequent molecular studies to better understand the viral life cycle and how to block it.

Abstract
mTORC1 regulates cellular growth and is activated by growth factors and by essential amino acids such as Leu. Leu enters cells via the Leu transporter LAT1-4F2hc (LAT1). Here we show that the Na+/K+/2Cl- cotransporter NKCC1 (SLC12A2), a known regulator of cell volume, is present in complex with LAT1. We further show that NKCC1 depletion or deletion enhances LAT1 activity, as well as activation of Akt and Erk, leading to activation of mTORC1 in cells, colonic organoids, and mouse colon. Moreover, NKCC1 depletion reduces intracellular Na+ concentration and cell volume (size) and mass and stimulates cell proliferation. NKCC1, therefore, suppresses mTORC1 by inhibiting its key activating signaling pathways. Importantly, by linking ion transport and cell volume regulation to mTORC1 function, NKCC1 provides a long-sought link connecting cell volume (size) to cell mass regulation.

Abstract
The nucleotide oligomerization domain (NOD)-like receptors 1 and 2 (NOD1/2) are intracellular pattern-recognition proteins that activate immune signaling pathways in response to peptidoglycans associated with microorganisms. Recruitment to bacteria-containing endosomes and other intracellular membranes is required for NOD1/2 signaling, and NOD1/2 mutations that disrupt membrane localization are associated with inflammatory bowel disease and other inflammatory conditions. However, little is known about this recruitment process. We found that NOD1/2 S-palmitoylation is required for membrane recruitment and immune signaling. ZDHHC5 was identified as the palmitoyltransferase responsible for this critical posttranslational modification, and several disease-associated mutations in NOD2 were found to be associated with defective S-palmitoylation. Thus, ZDHHC5-mediated S-palmitoylation of NOD1/2 is critical for their ability to respond to peptidoglycans and to mount an effective immune response.

Abstract
Mitochondria are subcellular organelles that are critical for meeting the bioenergetic and biosynthetic needs of the cell. Mitochondrial function relies on genes and RNA species encoded both in the nucleus and mitochondria, and on their coordinated translation, import and respiratory complex assembly. Here, we characterize EXD2 (exonuclease 3'-5' domain-containing 2), a nuclear-encoded gene, and show that it is targeted to the mitochondria and prevents the aberrant association of messenger RNAs with the mitochondrial ribosome. Loss of EXD2 results in defective mitochondrial translation, impaired respiration, reduced ATP production, increased reactive oxygen species and widespread metabolic abnormalities. Depletion of the Drosophila melanogaster EXD2 orthologue (CG6744) causes developmental delays and premature female germline stem cell attrition, reduced fecundity and a dramatic extension of lifespan that is reversed with an antioxidant diet. Our results define a conserved role for EXD2 in mitochondrial translation that influences development and ageing.

Abstract
The PAR-1-MARK pathway controls cell polarity through the phosphorylation of microtubule-associated proteins. Rho-Rac guanine nucleotide exchange factor 2 (ARHGEF2), which activates Ras homolog family member A (RHOA), is anchored to the microtubule network and sequestered in an inhibited state through binding to dynein light chain Tctex-1 type 1 (DYNLT1). We showed in mammalian cells that liver kinase B1 (LKB1) activated the microtubule affinity-regulating kinase 3 (MARK3), which in turn phosphorylated ARHGEF2 at Ser151 This modification disrupted the interaction between ARHGEF2 and DYNLT1 by generating a 14-3-3 binding site in ARHGEF2, thus causing ARHGEF2 to dissociate from microtubules. Phosphorylation of ARHGEF2 by MARK3 stimulated RHOA activation and the formation of stress fibers and focal adhesions, and was required for organized cellular architecture in three-dimensional culture. Protein phosphatase 2A (PP2A) dephosphorylated Ser151 in ARHGEF2 to restore the inhibited state. Thus, we have identified a regulatory switch controlled by MARK3 that couples microtubules to the actin cytoskeleton to establish epithelial cell polarity through ARHGEF2.

Abstract
Peroxisomes and the ER exchange lipids for various metabolic and anabolic reactions. In this study, Hua et al. show that the interaction between the ER-resident VAPs with the peroxisomal protein ACBD5 tethers peroxisomes to the ER. This tether is required for the exchange of lipids, including cholesterol, between the two organelles. Lipid exchange between the endoplasmic reticulum (ER) and peroxisomes is necessary for the synthesis and catabolism of lipids, the trafficking of cholesterol, and peroxisome biogenesis in mammalian cells. However, how lipids are exchanged between these two organelles is not understood. In this study, we report that the ER-resident VAMP-associated proteins A and B (VAPA and VAPB) interact with the peroxisomal membrane protein acyl-CoA binding domain containing 5 (ACBD5) and that this interaction is required to tether the two organelles together, thereby facilitating the lipid exchange between them. Depletion of either ACBD5 or VAP expression results in increased peroxisome mobility, suggesting that VAP–ACBD5 complex acts as the primary ER–peroxisome tether. We also demonstrate that tethering of peroxisomes to the ER is necessary for peroxisome growth, the synthesis of plasmalogen phospholipids, and the maintenance of cellular cholesterol levels. Collectively, our data highlight the importance of VAP–ACBD5–mediated contact between the ER and peroxisomes for organelle maintenance and lipid homeostasis.

Abstract
A bipolar mitotic spindle facilitates the equal segregation of chromosomes to two daughter cells. To achieve bipolar attachment of microtubules to kinetochores of sister chromatids, chromatids must remain paired after replication. This cohesion is mediated by the conserved cohesin complex comprised of SMC1, SMC3, SCC1, and either SA1 or SA2 in humans. Because defects in spindle assembly or sister chromatid cohesion can lead to aneuploidy in daughter cells, proper regulation of these processes is essential for fidelity in chromosome segregation. In an RNAi screen for regulators of spindle assembly, we identify the deubiquitinase USP37 as a regulator of mitotic progression, centrosome integrity, and chromosome alignment. USP37 associates with cohesin and contributes to sister chromatid resolution. Cohesion defects are rescued by expression of an RNAi-resistant USP37, but not the catalytically impaired USP37(C350A) mutant. Further, USP37 associates with WAPL, a negative regulator of cohesion necessary for cohesin release in prophase, in a manner dependent on USP37's second and third ubiquitin-interacting motifs. Depletion of USP37 reduces the stability of chromatin-associated WAPL and increases the fraction of WAPL that is more heavily ubiquitylated in mitosis. Consistently, overexpression of USP37(C350A) results in increased modification of WAPL, and addition of purified USP37(WT), but not USP37(C350A), to WAPL immunoprecipitates results in a reduction of ubiquitylated products. Taken together, our results ascribe a novel function for USP37 in mitotic progression and further suggest that USP37 positively regulates the stability of chromatin-associated WAPL to facilitate sister chromatid resolution.
