Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0003202
UniProt IDQ9UBT2
Primary gene name(s)UBA2
Synonym gene name(s)SAE2, UBLE1B
Protein nameSUMO-activating enzyme subunit 2
Protein functionThe 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. {ECO:0000269|PubMed:11451954, ECO:0000269|PubMed:11481243, ECO:0000269|PubMed:15660128, ECO:0000269|PubMed:17643372, ECO:0000269|PubMed:19443651, ECO:0000269|PubMed:20164921}.
Subcellular locationCytoplasm. Nucleus. Note=Shuttles between the cytoplasm and the nucleus, sumoylation is required either for nuclear translocation or nuclear retention.
