| UniProt Protein Function: | SAE2: a protein of the ubiquitin-activating E1 family. Acts as a UBL1 E1 ligase. Mediates ATP-dependent activation of UBL1 and formation of a thiolester with a conserved cysteine residue on SAE2. |
| UniProt Protein Details: | Protein type:Ubiquitin ligase; Motility/polarity/chemotaxis; EC 6.3.2.-; EC 6.3.2.19; Ubiquitin conjugating system; Ligase Chromosomal Location of Human Ortholog: 19q12 Cellular Component: nucleoplasm; cytosol; nucleus Molecular Function:SUMO activating enzyme activity; protein binding; protein heterodimerization activity; metal ion binding; enzyme activator activity; transcription factor binding; ATP binding Biological Process: positive regulation of catalytic activity; cellular protein metabolic process; protein sumoylation; SMT3-dependent protein catabolic process; post-translational protein modification |
| NCBI Summary: | 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] |
