Protein Information (annotations from UniProt)

Database IDHIV0007718
UniProt IDQ9C0C9
Primary gene name(s)UBE2O
Synonym gene name(s)KIAA1734
Protein name(E3-independent E2 ubiquitin-conjugating enzyme
Protein functionE2/E3 hybrid ubiquitin-protein ligase that displays both E2 and E3 ligase activities and mediates monoubiquitination of target proteins, PubMed:23455153, PubMed:24703950. Negatively regulates TRAF6-mediated NF-kappa-B activation independently of its E2 activity, PubMed:23381138. Acts as a positive regulator of BMP7 signaling by mediating monoubiquitination of SMAD6, thereby regulating adipogenesis, PubMed:23455153. Mediates monoubiquitination at different sites of the nuclear localization signal, NLS of BAP1, leading to cytoplasmic retention of BAP1. Also able to monoubiquitinate the NLS of other chromatin-associated proteins, such as INO80 and CXXC1, affecting their subcellular location, PubMed:24703950. Acts as a regulator of retrograde transport by assisting the TRIM27:MAGEL2 E3 ubiquitin ligase complex to mediate 'Lys-63'-linked ubiquitination of WASH1, leading to promote endosomal F-actin assembly, PubMed:23452853. {ECO:0000269|PubMed:23381138, ECO:0000269|PubMed:23452853, ECO:0000269|PubMed:23455153, ECO:0000269|PubMed:24703950}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:24703950}. Nucleus {ECO:0000269|PubMed:24703950}. Note=Mainly localizes to the cytoplasm.
