Facts about SUMO-activating enzyme subunit 2.
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..
