The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.5 - 2 µg/ml. Detects a band of approximately 71 kDa.
FunctionThe 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.
PathwayProtein modification; protein sumoylation.
Sequence similaritiesBelongs to the ubiquitin-activating E1 family.
