  • 21010
Name SUMO-activating enzyme subunit 1
Synonyms
  1. Ubiquitin-like 1-activating enzyme E1A
Gene Name SAE1
Protein Type Enzyme
Biological Properties
General Function Involved in catalytic activity
Specific Function 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
