Also showing Human UBA2

$260
100 µl
APPLICATIONS
REACTIVITY
Human, Monkey, Mouse, Rat

Application Methods: Immunoprecipitation, Western Blotting

Background: The process of SUMO conjugation to target proteins is similar to the molecular chain of events observed with ubiquitin (1). SUMO is conjugated to target proteins through the coordinated action of the cellular SUMO conjugation machinery consisting of E1, E2, and E3 enzymes (2). The canonical SUMO E1 activating enzyme is a heterodimer consisting of SAE1 (AOS1) and UBA2 (SAE2) subunits. Mature SUMO is activated by E1 in an ATP-dependent reaction that generates adenylated SUMO, which functions as a high-energy intermediate in the formation of a thioester linkage between SUMO and Cys173 of UBA2 (3,4). SUMO is subsequently transferred from UBA2 to the SUMO E2 conjugating enzyme, UBC9 (5). Recent evidence suggests that redox regulation of UBA2 serves as a physiologic mechanism to modulate the cellular level of sumoylated target proteins (6).
