CC   -!- FUNCTION: Accepts the ubiquitin-like protein NEDD8 from the UBA3-NAE1
CC       E1 complex and catalyzes its covalent attachment to other proteins. The
CC       specific interaction with the E3 ubiquitin ligase rbx1, but not rbx2,
CC       suggests that the rbx1-ube2m complex neddylates specific target
CC       proteins, such as cul1, cul2, cul3 and cul4. Involved in cell
CC       proliferation. {ECO:0000250|UniProtKB:P61081}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[E1 NEDD8-activating enzyme]-S-[NEDD8 protein]-yl-L-cysteine +
CC         [E2 NEDD8-conjugating enzyme]-L-cysteine = [E1 NEDD8-activating
CC         enzyme]-L-cysteine + [E2 NEDD8-conjugating enzyme]-S-[NEDD8-protein]-
CC         yl-L-cysteine.; EC=2.3.2.34; Evidence={ECO:0000250|UniProtKB:P61081};
CC   -!- PATHWAY: Protein modification; protein neddylation.
CC   -!- DOMAIN: Both the N-terminal docking peptide and the catalytic core
CC       domain must bind the uba3-nae1 complex simultaneously for optimal
CC       transfer of nedd8. {ECO:0000250}.
CC   -!- PTM: The acetylation of Met-1 increases affinity for DCUN1D1 by about 2
CC       orders of magnitude and is crucial for NEDD8 transfer to cullins.
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family. UBC12
CC       subfamily. {ECO:0000255|PROSITE-ProRule:PRU00388}.
