ARTICLE https://doi.org/10.1038/s41467-019-12388-y OPEN A tri-ionic anchor mechanism drives Ube2N-specific recruitment and K63-chain ubiquitination in TRIM ligases Leo Kiss1,4, Jingwei Zeng 1,4, Claire F. Dickson1,2, Donna L. Mallery1, Ji-Chun Yang 1, Stephen H. McLaughlin 1, Andreas Boland1,3, David Neuhaus1,5 & Leo C. James1,5* 1234567890():,; The cytosolic antibody receptor TRIM21 possesses unique ubiquitination activity that drives broad-spectrum anti-pathogen targeting and underpins the protein depletion technology Trim-Away. This activity is dependent on formation of self-anchored, K63-linked ubiquitin chains by the heterodimeric E2 enzyme Ube2N/Ube2V2. Here we reveal how TRIM21 facilitates ubiquitin transfer and differentiates this E2 from other closely related enzymes. A tri-ionic motif provides optimally distributed anchor points that allow TRIM21 to wrap an Ube2N~Ub complex around its RING domain, locking the closed conformation and promoting ubiquitin discharge. Mutation of these anchor points inhibits ubiquitination with Ube2N/ Ube2V2, viral neutralization and immune signalling. We show that the same mechanism is employed by the anti-HIV restriction factor TRIM5 and identify spatially conserved ionic anchor points in other Ube2N-recruiting RING E3s. The tri-ionic motif is exclusively required for Ube2N but not Ube2D1 activity and provides a generic E2-specific catalysis mechanism for RING E3s. 1 Medical Research Council Laboratory of Molecular Biology, Cambridge, UK. 2Present address: University of New South Wales, Sydney, NSW, Australia. 3Present address: Department of Molecular Biology, Science III, University of Geneva, Geneva, Switzerland. 4These authors contributed equally: Leo Kiss, Jingwei Zeng. 5These authors jointly supervised: David Neuhaus, Leo C. -

HRD1 and UBE2J1 Target Misfolded MHC Class I Heavy Chains for Endoplasmic Reticulum- Associated Degradation
HRD1 and UBE2J1 target misfolded MHC class I heavy chains for endoplasmic reticulum- associated degradation Marian L. Burr, Florencia Cano, Stanislava Svobodova, Louise H. Boyle, Jessica M. Boname, and Paul J. Lehner1 Cambridge Institute for Medical Research, University of Cambridge, Cambridge CB2 0XY, United Kingdom Edited* by Peter Cresswell, Yale University School of Medicine, New Haven, CT, and approved December 21, 2010 (received for review October 29, 2010) The assembly of MHC class I molecules is governed by stringent orthologs of yeast Hrd1p, HRD1 (Synoviolin) and gp78 (AMFR), endoplasmic reticulum (ER) quality control mechanisms. MHC class I have distinct substrate specificities, exemplifying the increased heavy chains that fail to achieve their native conformation in complexity of mammalian ERAD (6, 7). HRD1 is implicated in the complex with β2-microglobulin (β2m) and peptide are targeted for pathogenesis of rheumatoid arthritis (10), and reported substrates ER-associated degradation. This requires ubiquitination of the MHC include α1-antitrypsin variants (11) and amyloid precursor protein class I heavy chain and its dislocation from the ER to the cytosol for (12). Three E2 ubiquitin-conjugating enzymes function in mam- proteasome-mediated degradation, although the cellular machin- malian ERAD: UBE2J1 and UBE2J2 (yeast Ubc6p orthologs) and ery involved in this process is unknown.

Ubiquitination and modification by UBLs share a similar catalytic cascade which requires the sequential action of three classes of enzymes: E1 activating enzymes, E2 conjugating enzymes and E3 ligases. Recent research has linked dysregulation of the Ub/UBLs modification system to numerous diseases including cancer, immunological disorders and neurodegeneration. Thus, the high substrate specificity provided by combinations of over 30 E2’s and over 600 E3’s makes these enzymes emerging drug targets. In response to a growing market demand, SignalChem has developed an extensive array of products encompassing enzymes, Ub/UBL modifiers and substrates in the ubiquitination, SUMOylation, ISGylation and NEDDylation processes. Using Promega’s AMP-GloTM technology and an optimized assay protocol, we have identified and validated a variety of functional combinations of the enzyme components. With the established protocol, each enzyme in the catalytic cascade has been assessed for their activity towards generation of free AMP. In addition, inhibition profiles of the ubiquitinating enzymes have been obtained using the assay system, further demonstrating their potential to be used in high-throughput screening to identify lead compounds for drug discovery and development programs. -
Comparative Analysis of the Ubiquitin-Proteasome System in Homo Sapiens and Saccharomyces Cerevisiae
Comparative Analysis of the Ubiquitin-proteasome system in Homo sapiens and Saccharomyces cerevisiae Inaugural-Dissertation zur Erlangung des Doktorgrades der Mathematisch-Naturwissenschaftlichen Fakultät der Universität zu Köln vorgelegt von Hartmut Scheel aus Rheinbach Köln, 2005 Berichterstatter: Prof. Dr. R. Jürgen Dohmen Prof. Dr. Thomas Langer Dr. Kay Hofmann Tag der mündlichen Prüfung: 18.07.2005 Zusammenfassung I Zusammenfassung Das Ubiquitin-Proteasom System (UPS) stellt den wichtigsten Abbauweg für intrazelluläre Proteine in eukaryotischen Zellen dar. Das abzubauende Protein wird zunächst über eine Enzym-Kaskade mit einer kovalent gebundenen Ubiquitinkette markiert. Anschließend wird das konjugierte Substrat vom Proteasom erkannt und proteolytisch gespalten. Ubiquitin besitzt eine Reihe von Homologen, die ebenfalls posttranslational an Proteine gekoppelt werden können, wie z.B. SUMO und NEDD8. Die hierbei verwendeten Aktivierungs- und Konjugations-Kaskaden sind vollständig analog zu der des Ubiquitin- Systems. Es ist charakteristisch für das UPS, daß sich die Vielzahl der daran beteiligten Proteine aus nur wenigen Proteinfamilien rekrutiert, die durch gemeinsame, funktionale Homologiedomänen gekennzeichnet sind. Einige dieser funktionalen Domänen sind auch in den Modifikations-Systemen der Ubiquitin-Homologen zu finden, jedoch verfügen diese Systeme zusätzlich über spezifische Domänentypen. Homologiedomänen lassen sich als mathematische Modelle in Form von Domänen- deskriptoren (Profile) beschreiben. Diese Deskriptoren können wiederum dazu verwendet werden, mit Hilfe geeigneter Verfahren eine gegebene Proteinsequenz auf das Vorliegen von entsprechenden Homologiedomänen zu untersuchen. Da die im UPS involvierten Homologie- domänen fast ausschließlich auf dieses System und seine Analoga beschränkt sind, können domänen-spezifische Profile zur Katalogisierung der UPS-relevanten Proteine einer Spezies verwendet werden. Auf dieser Basis können dann die entsprechenden UPS-Repertoires verschiedener Spezies miteinander verglichen werden. -
Protein Folding and Quality Control in the ER

The ERQC facilitates folding and modification of secretory and mem- brane proteins and eliminates terminally misfolded polypeptides through ER-associated degradation (ERAD) or autophagic degradation. This mechanism of ER protein surveillance is closely linked to redox and calcium homeostasis in the ER, whose balance is presumed to be regulated by a specific cellular compartment. The potential to modulate proteostasis and metabolism with chemical compounds or targeted siRNAs may offer an ideal option for the treatment of disease. he endoplasmic reticulum (ER) serves as a complex in the ER membrane (Johnson and Tprotein-folding factory where elaborate Van Waes 1999; Saraogi and Shan 2011).
