SAE1 blocking peptide

Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1; MIM 61912), or sumoylation, regulates protein structure and intracellular localization. SAE1 and UBA2 (MIM 613295) form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins (Okuma et al., 1999 [PubMed 99283]).[supplied by OMIM, Mar 21]
