Protein existence	Evidence at protein level

General annotation (Comments)

Function	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.6 Ref.7 Ref.8
Enzyme regulation	Binding of TP53BP2 to the regulatory subunit NAE1 decreases activity.
Pathway	Protein modification; protein neddylation.
Subunit structure	Heterodimer of UBA3 and NAE1. Interacts with NEDD8, UBE2F and UBE2M. Binds ESR1 and ESR2 with bound steroid ligand By similarity. Ref.8
Tissue specificity	Ubiquitously expressed. Ref.6
Miscellaneous	Arg-211 acts as a selectivity gate, preventing misactivation of ubiquitin by this NEDD8-specific E1 complex.
Sequence similarities	Belongs to the ubiquitin-activating E1 family. UBA3 subfamily.
Sequence caution	The sequence AAC27648.1 differs from that shown. Reason: Erroneous initiation.
