UBE2D4 (Ubiquitin Conjugating Enzyme E2 D4 (Putative)) is a Protein Coding gene. Among its related pathways are Protein processing in endoplasmic reticulum and Protein ubiquitination. 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 able to promote polyubiquitination using all 7 ubiquitin Lys residues, but may prefer Lys-11 and Lys-48-linked polyubiquitination.
