General annotation (Comments)

Function	Accepts the ubiquitin-like protein NEDD8 from the UBA3-NAE1 E1 complex and catalyzes its covalent attachment to other proteins. Involved in cell proliferation.
Catalytic activity	ATP + NEDD8 + protein lysine = AMP + diphosphate + protein N-NEDD8yllysine.
Pathway	Protein modification; protein neddylation.
Subunit structure	Interacts with UBA3.
Domain	Both the N-terminal docking peptide and the catalytic core domain must bind the UBA3-NAE1 complex simultaneously for optimal transfer of NEDD8.
Sequence similarities	Belongs to the ubiquitin-conjugating enzyme family. UBC12 subfamily.
