UBE2Q2 (Ubiquitin Conjugating Enzyme E2 Q2) is a Protein Coding gene. Among its related pathways are Protein ubiquitination and Class I MHC mediated antigen processing and presentation. GO annotations related to this gene include ligase activity and acid-amino acid ligase activity. Accepts ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. In vitro catalyzes Lys-48-linked polyubiquitination.
