hUbc12, NEDD8 carrier protein, NEDD8 conjugating enzyme Ubc12, NEDD8 protein ligase, NEDD8-conjugating enzyme Ubc12, UBC-RS2, UBC12, UBC12_HUMAN, ube2m, ubiquitin carrier protein M, Ubiquitin conjugating enzyme E2 M, Ubiquitin-conjugating enzyme E2 M, ubiquitin-protein ligase M, yeast UBC12 homolog.
Accepts the ubiquitin-like protein NEDD8 from the UBA3-NAE1 E1 complex and catalyzes its covalent attachment to other proteins. The specific interaction with the E3 ubiquitin ligase RBX1, but not RBX2, suggests that the RBX1-UBE2M complex neddylates specific target proteins, such as CUL1, CUL2, CUL3 and CUL4. Involved in cell proliferation.
