Function

SAE1_HUMAN The heterodimer acts as a 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.^[1] ^[2] ^[3] ^[4] ^[5] ^[6] ^[7]
