FunctionRegulatory subunit of the dimeric UBA3-NAE1 E1 enzyme. E1 activates NEDD8 by first adenylating its C-terminal glycine residue with ATP, thereafter linking this residue to the side chain of the catalytic cysteine, yielding a NEDD8-UBA3 thioester and free AMP. E1 finally transfers NEDD8 to the catalytic cysteine of UBE2M. Necessary for cell cycle progression through the S-M checkpoint. Overexpression of NAE1 causes apoptosis through deregulation of NEDD8 conjugation.
Tissue specificityUbiquitous in fetal tissues. Expressed throughout the adult brain.
PathwayProtein modification; protein neddylation.
Sequence similaritiesBelongs to the ubiquitin-activating E1 family. ULA1 subfamily.
Cellular localizationCell membrane. Colocalizes with APP in lipid rafts.
