DESCRIPTION

Also known as UB2G2_HUMAN, UBE2G2, UBC7. Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins (PubMed:20061386). In vitro catalyzes 'Lys-48'-linked polyubiquitination (PubMed:20061386). Involved in endoplasmic reticulum-associated degradation (ERAD) (PubMed:22607976). Required for sterol-induced ubiquitination of 3-hydroxy-3-methylglutaryl coenzyme A reductase and its subsequent proteasomal degradation (PubMed:23223569). Interacts with AUP1 (via C-terminus); the interaction recruits UBE2G2 to lipid droplets (PubMed:21127063, PubMed:21857022, PubMed:23223569). Interacts with ubiquitin ligases AMFR/gp78 and RNF139/TRC8; recruitment to lipid droplets by AUP1 facilitates interaction of UBE2G2 with AMFR and RNF139, leading to sterol-induced ubiquitination of 3-hydroxy-3-methylglutaryl coenzyme A reductase and its subsequent proteasomal degradation (PubMed:23223569).
