FunctionAccepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes 'Lys-11'-linked polyubiquitination. Involved in the selective degradation of short-lived and abnormal proteins. Down-regulated during the S-phase it is involved in progression through the cell cycle. Regulates nuclear hormone receptors transcriptional activity. May play a role in myelopoiesis.
Tissue specificityUbiquitous, with highest expression in testis.
PathwayProtein modification; protein ubiquitination.
Sequence similaritiesBelongs to the ubiquitin-conjugating enzyme family.
Post-translational modificationsUbiquitinated. The alteration of UBE2L3 protein levels during the S-phase of the cell cycle is due to ubiquitin-dependent proteasomal degradation.
