Autoinhibition Mechanism of the Ubiquitin-Conjugating Enzyme UBE2S by Autoubiquitination [PDF]
Structure, 2019 Ubiquitin-conjugating enzymes (E2s) govern key aspects of ubiquitin signaling. Emerging evidence suggests that the activities of E2s are modulated by posttranslational modifications; the structural underpinnings, however, are largely unclear. Here, we unravel the structural basis and mechanistic consequences of a conserved autoubiquitination event near

Advanced Science, EarlyView.CCDC41 is essential for meiotic maturation in mouse oocytes through regulating Rab7‐positive endosomes fusion with lysosomes and Rab11a‐positive vesicle fusion with the plasma membrane. Abstract Coiled‐coil domain‐containing protein 41 (CCDC41), a core component of centriolar distal appendages involved in centriole assembly and ciliary vesicle docking,

In vitro Ubiquitin Dimer Formation Assay
Bio-Protocol, 2017 The process of protein ubiquitination typically consists of three sequential steps to add an ubiquitin (Ub) or Ub chain to a substrate protein, requiring three different enzymes, ubiquitin activating enzyme (E1), ubiquitin conjugating enzyme (E2), and ...

Sequence of a Cloned Tomato Ubiquitin Conjugating Enzyme
Plant Physiology, 1993 Ubiquitin is a small, abundant protein that is seemingly present in a11 eukaryotic cells and that is covalently ligated to specific protein substrates via an ATP-dependent reaction. This ubiquitinous has been demonstrated to target proteins for subsequent cellular degradation.

A Giant Ubiquitin-conjugating Enzyme Related to IAP Apoptosis Inhibitors [PDF]
The Journal of Cell Biology, 1998 Ubiquitin-conjugating enzymes (UBC) catalyze the covalent attachment of ubiquitin to target proteins and are distinguished by the presence of a UBC domain required for catalysis. Previously identified members of this enzyme family are small proteins and function primarily in selective proteolysis pathways.

Advanced Science, EarlyView.RA of EEAR inhibits TGF‐β1 ubiquitination and changes conformation by target binding TGF‐β1, regulating TGF‐β1/Smad2/3 signaling pathway. Thus it down‐regulated downstream protein expression, inhibited EMT and collagen deposition of ECM, in order to EEAR preventing PF in COPD.

E2 ubiquitin-conjugating enzymes regulate the deubiquitinating activity of OTUB1 [PDF]
Nature Structural & Molecular Biology, 2013 OTUB1 is a Lys48-specific deubiquitinating enzyme that forms a complex in vivo with E2 ubiquitin (Ub)-conjugating enzymes including UBC13 and UBCH5. OTUB1 binds E2~Ub thioester intermediates and prevents ubiquitin transfer, thereby noncatalytically inhibiting accumulation of polyubiquitin.

Neddylation Targets and Stabilizes NLRP3 to Augment Inflammasome‐Mediated Colitis and Mood Disorder
Advanced Science, EarlyView.NLRP3 inflammasome contributes to colitis and mood disorder. This study demonstrates that neddylation targets NLRP3 at K287, which hinders its interaction with K48‐linked ubiquitination E3 Trim31 and thereby stabilizes it. Neddylation blockade in myeloid cells and microglia mitigates DSS‐induced colitis and psychological stress‐induced anxiety‐like ...

TULIP2: An Improved Method for the Identification of Ubiquitin E3-Specific Targets
Frontiers in Chemistry, 2019 Protein modification by Ubiquitin or Ubiquitin-like modifiers is mediated by an enzyme cascade composed of E1, E2, and E3 enzymes. E1s, or ubiquitin-activating enzymes, perform ubiquitin activation. Next, ubiquitin is transferred to ubiquitin-conjugating
