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. {ECO:0000269|PubMed:11451954, ECO:0000269|PubMed:11481243, ECO:0000269|PubMed:15660128, ECO:0000269|PubMed:17643372, ECO:0000269|PubMed:19443651, ECO:0000269|PubMed:20164921}. |UBACT| |ThiF| |UBA e1 thiolCys| |SUMO activating enzyme activity| |SUMO activating enzyme complex| |small protein activating enzyme binding| |ubiquitin-like protein conjugating enzyme binding| |SUMO binding| |enzyme activator activity| |transferase activity| |protein sumoylation| |magnesium ion binding| |peptidyl-lysine modification| |transcription factor binding| |protein heterodimerization activity| |protein modification by small protein conjugation| |peptidyl-amino acid modification| |protein modification by small protein conjugation or removal| |positive regulation of catalytic activity| |ATP binding| |positive regulation of molecular function| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp19|Etoposide 1μM R00 exp19]]|-2| |[[:results:exp70|INK128 0.2μM R02 exp70]]|-1.77| |[[:results:exp512|Olaparib 4μM R08 exp512]]|-1.73| |[[:results:exp414|Tozasertib 0.1μM R07 exp414]]|-1.73| |[[:results:exp299|Talazoparib 0.006μM R06 exp299]]|4.83| ^Gene^Correlation^ |[[:human genes:s:sae1|SAE1]]|0.475| Global Fraction of Cell Lines Where Essential: 678/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|1/1| |909776.0|1/1| |bile duct|24/28| |blood|24/28| |bone|25/26| |breast|31/33| |central nervous system|54/56| |cervix|4/4| |colorectal|16/17| |esophagus|10/13| |fibroblast|1/1| |gastric|15/16| |kidney|21/21| |liver|16/20| |lung|68/75| |lymphocyte|16/16| |ovary|24/26| |pancreas|22/24| |peripheral nervous system|15/16| |plasma cell|13/15| |prostate|1/1| |skin|21/24| |soft tissue|9/9| |thyroid|2/2| |upper aerodigestive|20/22| |urinary tract|28/29| |uterus|4/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1385 * **Expression level (log2 read counts)**: 7.05 {{:chemogenomics:nalm6 dist.png?nolink |}}
