Abstract

Deregulation of the HECT ubiquitin ligase UBE3A/E6AP has been implicated in Angelman syndrome as well as autism spectrum disorders. We and others have previously identified the 26S proteasome as one of the major UBE3A-interacting protein complexes. Here, we characterize the interaction of UBE3A and the proteasomal subunit PSMD4 (Rpn10/S5a). We map the interaction to the highly conserved Zn2+-binding N-terminal (AZUL) domain of UBE3A, the integrity of which is crucial for binding to PSMD4. Interestingly, two Angelman syndrome point mutations that affect the AZUL domain show an impaired ability to bind PSMD4. Although not affecting the ubiquitin ligase or the estrogen receptor α-mediated transcriptional regulation activities, these AZUL domain mutations prevent UBE3A from stimulating the Wnt/β-catenin signaling pathway. Taken together, our data indicate that impaired binding to the 26S proteasome and consequential deregulation of Wnt/β-catenin signaling might contribute to the functional defect of these mutants in Angelman syndrome.

Abstract

© 2018 Elsevier Inc., To identify novel genes associated with ALS, we undertook two lines of investigation. We carried out a genome-wide association study comparing 20,806 ALS cases and 59,804 controls. Independently, we performed a rare variant burden analysis comparing 1,138 index familial ALS cases and 19,494 controls. Through both approaches, we identified kinesin family member 5A (KIF5A) as a novel gene associated with ALS. Interestingly, mutations predominantly in the N-terminal motor domain of KIF5A are causative for two neurodegenerative diseases: hereditary spastic paraplegia (SPG10) and Charcot-Marie-Tooth type 2 (CMT2). In contrast, ALS-associated mutations are primarily located at the C-terminal cargo-binding tail domain and patients harboring loss-of-function mutations displayed an extended survival relative to typical ALS cases. Taken together, these results broaden the phenotype spectrum resulting from mutations in KIF5A and strengthen the role of cytoskeletal defects in the pathogenesis of ALS.

Abstract

HERC2 is a large E3 ubiquitin ligase with multiple structural domains that has been implicated in an array of cellular processes. Mutations in HERC2 are linked to developmental delays and impairment caused by nervous system dysfunction, such as Angelman Syndrome and autism-spectrum disorders. However, HERC2 cellular activity and regulation remain poorly understood. We used a broad proteomic approach to survey the landscape of cellular proteins that interact with HERC2. We identified nearly 300 potential interactors, a subset of which we validated binding to HERC2. The potential HERC2 interactors included the eukaryotic translation initiation factor 3 complex, the intracellular transport COPI coatomer complex, the glycogen regulator phosphorylase kinase, beta-catenin, PI3 kinase, and proteins involved in fatty acid transport and iron homeostasis. Through a complex bioinformatic analysis of potential interactors, we linked HERC2 to cellular processes including intracellular protein trafficking and transport, metabolism of cellular energy, and protein translation. Given its size, multidomain structure, and association with various cellular activities, HERC2 may function as a scaffold to integrate protein complexes and bridge critical cellular pathways. This work provides a significant resource with which to interrogate HERC2 function more deeply and evaluate its contributions to mechanisms governing cellular homeostasis and disease.

Abstract

We have begun to define the human papillomavirus (HPV)-associated proteome for a subset of the more than 120 HPV types that have been identified to date. Our approach uses a mass spectrometry-based platform for the systematic identification of interactions between human papillomavirus and host cellular proteins, and here we report a proteomic analysis of the E6 proteins from 16 different HPV types. The viruses included represent high-risk, low-risk, and non-cancer-associated types from genus alpha as well as viruses from four different species in genus beta. The E6 interaction data set consists of 153 cellular proteins, including several previously reported HPV E6 interactors such as p53, E6AP, MAML1, and p300/CBP and proteins containing PDZ domains. We report the genus-specific binding of E6s to either E6AP or MAML1, define the specific HPV E6s that bind to p300, and demonstrate several new features of interactions involving beta HPV E6s. In particular, we report that several beta HPV E6s bind to proteins containing PDZ domains and that at least two beta HPV E6s bind to p53. Finally, we report the newly discovered interaction of proteins of E6 of beta genus, species 2, with the Ccr4-Not complex, the first report of a viral protein binding to this complex. This data set represents a comprehensive survey of E6 binding partners that provides a resource for the HPV field and will allow continued studies on the diverse biology of the human papillomaviruses.

Abstract

Background: Deubiquitylases (DUBs) oppose the action of E3-ligases and influence key signalling pathways. Results: USP15 stabilizes the E3 ligase BRAP/IMP, regulates CRAF expression, and is a positive regulator of MEK. Conclusion: USP15 is a positive regulator of the MAPK pathway while stabilizing the E3 ligase BRAP/IMP. Significance: Evidence is provided for novel modes of MAPK pathway regulation by DUBs., The opposing regulators of ubiquitylation status, E3 ligases and deubiquitylases, are often found to be associated in complexes. Here we report on a novel interaction between the E3 ligase BRAP (also referred to as IMP), a negative regulator of the MAPK scaffold protein KSR, and two closely related deubiquitylases, USP15 and USP4. We map the interaction to the N-terminal DUSP-UBL domain of USP15 and the coiled coil region of BRAP. USP15 as well as USP4 oppose the autoubiquitylation of BRAP, whereas BRAP promotes the ubiquitylation of USP15. Importantly, USP15 but not USP4 depletion destabilizes BRAP by promoting its proteasomal degradation, and BRAP-protein levels can be rescued by reintroducing catalytically active but not inactive mutant USP15. Unexpectedly, USP15 depletion results in a decrease in amplitude of MAPK signaling in response to EGF and PDGF. We provide evidence for a model in which the dominant effect of prolonged USP15 depletion upon signal amplitude is due to a decrease in CRAF levels while allowing for the possibility that USP15 may also function to dampen MAPK signaling through direct stabilization of a negative regulator, the E3 ligase BRAP.

Abstract

A localization atlas is provided for 66 of 90 mammalian GFP-tagged deubiquitinases (DUBs). USP21 is the only DUB in the panel that localizes to both microtubules and the centrosome. Functional data suggest a key role for USP21 in the choreography of microtubule reorganization., Ubiquitination is a reversible modification that influences a broad range of physiological processes. There are approximately 90 deubiquitinases (DUBs) encoded in the human genome, of which 79 are predicted to have catalytic activity. We tagged 66 DUBs with green fluorescent protein and systematically surveyed their subcellular distribution, identifying enzymes specific to the nucleus, plasma membrane, and secretory and endocytic pathways. USP21 is unique in showing clear association with both centrosomes and microtubules. Using an in vitro assay, we show that microtubule binding is direct and identify a novel microtubule-binding motif encompassed within amino acids 59–75 of the N-terminus of USP21. Our functional studies indicate a key role for USP21 in the governance of microtubule- and centrosome-associated physiological processes: Depletion of USP21 in A549 cells compromises the reestablishment of a radial array of microtubules during recovery from cold-induced depolymerization and also reduces the probability of primary cilium formation, whereas USP21 knockdown in PC12 cells inhibits nerve growth factor–induced neurite outgrowth.

Abstract

Database searches can fail to detect all truly homologous sequences, particularly when dealing with short, highly sequence diverse protein families. Here, using microtubule interacting and transport (MIT) domains as an example, we have applied an approach of profile–profile matching followed by ab initio structure modelling to the detection of true homologues in the borderline significant zone of database searches. Novel MIT domains were confidently identified in USP54, containing an apparently inactive ubiquitin carboxyl-terminal hydrolase domain, a katanin-like ATPase KATNAL1, and an uncharacterized protein containing a VPS9 domain. As a proof of principle, we have confirmed the novel MIT annotation for USP54 by in vitro profiling of binding to CHMP proteins.Structured summaryUSP8 binds:CHMPs 1A 1B 2A 2B 4CUSP54 binds:CHMPs 1B 2A 2B 4C 6

Abstract

Autophagy is a conserved process that delivers components of the cytoplasm to lysosomes for degradation. The E1 and E2 enzymes encoded by Atg7 and Atg3 are thought to be essential for autophagy involving the ubiquitin-like protein Atg8. Here, we describe an Atg7- and Atg3-independent autophagy pathway that facilitates programmed reduction of cell size during intestine cell death. Although multiple components of the core autophagy pathways, including Atg8, are required for autophagy and cells to shrink in the midgut of the intestine, loss of either Atg7 or Atg3 function does not influence these cellular processes. Rather, Uba1, the E1 enzyme used in ubiquitylation, is required for autophagy and reduction of cell size. Our data reveal that distinct autophagy programs are used by different cells within an animal, and disclose an unappreciated role for ubiquitin activation in autophagy.

Abstract

Summary Mitochondrial sirtuins, SIRT3–5, are NAD + -dependent deacylases and ADP-ribosyltransferases that are critical for stress responses. However, a comprehensive understanding of sirtuin targets, regulation of sirtuin activity, and the relationships between sirtuins remains a key challenge in mitochondrial physiology. Here, we employ systematic interaction proteomics to elucidate the mitochondrial sirtuin protein interaction landscape. This work reveals sirtuin interactions with numerous functional modules within mitochondria, identifies candidate sirtuin substrates, and uncovers a fundamental role for sequestration of SIRT3 by ATP synthase in mitochondrial homeostasis. In healthy mitochondria, a pool of SIRT3 binds ATP synthase, but upon matrix pH reduction with concomitant loss of mitochondrial membrane potential, SIRT3 dissociates. This release correlates with rapid deacetylation of matrix proteins, and SIRT3 is required for recovery of membrane potential. In vitro reconstitution experiments, as well as analysis of CRISPR/Cas9-engineered cells, indicate that pH-dependent SIRT3 release requires H135 in the ATP5O subunit of ATP synthase. Our SIRT3–5 interaction network provides a framework for discovering novel biological functions regulated by mitochondrial sirtuins.

Abstract

More than 120 human papillomaviruses (HPVs) have now been identified and have been associated with a variety of clinical lesions. To understand the molecular differences among these viruses that result in lesions with distinct pathologies, we have begun a MS-based proteomic analysis of HPV–host cellular protein interactions and have created the plasmid and cell line libraries required for these studies. To validate our system, we have characterized the host cellular proteins that bind to the E7 proteins expressed from 17 different HPV types. These studies reveal a number of interactions, some of which are conserved across HPV types and others that are unique to a single HPV species or HPV genus. Binding of E7 to UBR4/p600 is conserved across all virus types, whereas the cellular protein ENC1 binds specifically to the E7s from HPV18 and HPV45, both members of genus alpha, species 7. We identify a specific interaction of HPV16 E7 with ZER1, a substrate specificity factor for a cullin 2 (CUL2)-RING ubiquitin ligase, and show that ZER1 is required for the binding of HPV16 E7 to CUL2. We further show that ZER1 is required for the destabilization of the retinoblastoma tumor suppressor RB1 in HPV16 E7-expressing cells and propose that a CUL2–ZER1 complex functions to target RB1 for degradation in HPV16 E7-expressing cells. These studies refine the current understanding of HPV E7 functions and establish a platform for the rapid identification of virus–host interactions.

Abstract

We have identified and characterized a Microtubule Interacting and Transport (MIT) domain at the N terminus of the deubiquitinating enzyme UBPY/USP8. In common with other MIT-containing proteins such as AMSH and VPS4, UBPY can interact with CHMP proteins, which are known to regulate endosomal sorting of ubiquitinated receptors. Comparison of binding preferences for the 11 members of the human CHMP family between the UBPY MIT domain and another ubiquitin isopeptidase, AMSH, reveals common interactions with CHMP1A and CHMP1B but a distinct selectivity of AMSH for CHMP3/VPS24, a core subunit of the ESCRT-III complex, and UBPY for CHMP7. We also show that in common with AMSH, UBPY deubiquitinating enzyme activity can be stimulated by STAM but is unresponsive to its cognate CHMPs. The UBPY MIT domain is dispensable for its catalytic activity but is essential for its localization to endosomes. This is functionally significant as an MIT-deleted UBPY mutant is unable to rescue its binding partner STAM from proteasomal degradation or reverse a block to epidermal growth factor receptor degradation imposed by small interfering RNA-mediated depletion of UBPY.
