RT   E1.";
RL   Nature 463:906-912(2010).
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   -!- PATHWAY: Protein modification; protein sumoylation.
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   -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus. Note=Shuttles between the
CC       cytoplasm and the nucleus, sumoylation is required either for nuclear
CC       translocation or nuclear retention.

CC       Name=2;
CC         IsoId=Q9UBT2-2; Sequence=VSP_056164;
CC   -!- PTM: Sumoylated with SUMO1 and SUMO2/3 and by UBC9. Sumoylation at Lys-
CC       236 inhibits enzymatic activity. Sumoylation at the C-terminal lysine
CC       cluster plays an essential role in nuclear trafficking.
CC       {ECO:0000269|PubMed:22403398, ECO:0000269|PubMed:23095757}.
CC   -!- SIMILARITY: Belongs to the ubiquitin-activating E1 family.
