[[http://www.uniprot.org/uniprot/UBA3_HUMAN UBA3_HUMAN]] Catalytic 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. Down-regulates steroid receptor activity. Necessary for cell cycle progression.<ref>PMID:10207026</ref> <ref>PMID:9694792</ref> <ref>PMID:12740388</ref> [[http://www.uniprot.org/uniprot/UBE2F_HUMAN UBE2F_HUMAN]] 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 RBX2, but not RBX1, suggests that the RBX2-UBE2F complex neddylates specific target proteins, such as CUL5.
