Protein Name:
SUMO-activating enzyme subunit 2
|
UniprotKB/SwissProt ID: Q9UBT2 (Q9UBT2)
Gene Name:
UBA2
Organism: Homo sapiens (Human)
Function: The heterodimer acts as an E1 ligase for SUMO1, SUMO2, SUMO3, and probably SUMO4. It mediates ATP-dependent activation of SUMO proteins followed by formation of a thioester bond between a SUMO protein and a conserved active site cysteine residue on UBA2/SAE2
