CC -!- FUNCTION: The heterodimer acts as an E1 ligase for SUMO1, SUMO2, SUMO3,
CC and probably SUMO4. It mediates ATP-dependent activation of SUMO
CC proteins followed by formation of a thioester bond between a SUMO
CC protein and a conserved active site cysteine residue on UBA2/SAE2.
CC {ECO:0000256|PIRNR:PIRNR039133}.
CC -!- PATHWAY: Protein modification; protein sumoylation.
CC {ECO:0000256|ARBA:ARBA00004718, ECO:0000256|PIRNR:PIRNR039133}.
CC -!- SUBUNIT: Heterodimer of SAE1 and UBA2/SAE2. The heterodimer corresponds
CC to the two domains that are encoded on a single polypeptide chain in
CC ubiquitin-activating enzyme E1. Interacts with UBE2I.
CC {ECO:0000256|ARBA:ARBA00026003}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000256|PIRNR:PIRNR039133}.
CC -!- SIMILARITY: Belongs to the ubiquitin-activating E1 family.
CC {ECO:0000256|ARBA:ARBA00005673, ECO:0000256|PIRNR:PIRNR039133}.
