UBA2

Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1; MIM 601912), or sumoylation, regulates protein structure and intracellular localization. SAE1 (MIM 613294) and UBA2 form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins (Okuma et al., 1999 [PubMed 9920803]).[supplied by OMIM, Mar 2010]
Protein class

Metabolic proteins

Predicted location

Intracellular, Membrane (different isoforms)

Single cell type specificity

Cell type enhanced (Sertoli cells)

Immune cell specificity

Low immune cell specificity

Cell line specificity

Low cell line specificity

Interaction

Heterodimer of SAE1 and UBA2/SAE2. The heterodimer corresponds to the two domains that are encoded on a single polypeptide chain in ubiquitin-activating enzyme E1. Interacts with UBE2I.

Molecular function

Transferase
