This protein suppresses the transcription factor E2F1-induced apoptosis and also interacts with, and negatively regulates Acinus, a nuclear factor involved in apoptotic DNA fragmentation. Its depletion enhances the cytotoxic action of the chemotherapeutic drugs. Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Aug 2011]. * **UniProt Summary**: Antiapoptotic factor that may have a role in protein assembly. Negatively regulates ACIN1. By binding to ACIN1, it suppresses ACIN1 cleavage from CASP3 and ACIN1-mediated DNA fragmentation. Also known to efficiently suppress E2F1-induced apoptosis. Its depletion enhances the cytotoxic action of the chemotherapeutic drugs. {ECO:0000269|PubMed:10780674, ECO:0000269|PubMed:17112319, ECO:0000269|PubMed:19387494}. |API5| |negative regulation of fibroblast apoptotic process| |regulation of fibroblast apoptotic process| |fibroblast growth factor binding| |spliceosomal complex| |nuclear speck| |negative regulation of apoptotic process| |negative regulation of programmed cell death| |apoptotic process| |negative regulation of cell death| |programmed cell death| |cell death| |RNA binding| |regulation of apoptotic process| |regulation of programmed cell death| |regulation of cell death| |membrane| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp290|LLY-283 2.6μM R06 exp290]]|-2.75| |[[:results:exp125|GSK461364A 0.005μM R03 exp125]]|-2.17| |[[:results:exp95|BI-2536 0.0042μM R03 exp95]]|-2.1| |[[:results:exp128|GSK591 2.6μM R03 exp128]]|-2.09| |[[:results:exp97|BI-6727 0.0125μM R03 exp97]]|-1.78| |[[:results:exp500|LY2090314 0.003μM R08 exp500 no dilution day6]]|-1.77| |[[:results:exp363|GSK-J4 1-1.25μM to day4 R07 exp363]]|1.77| |[[:results:exp362|GSK-J4 1μM R07 exp362]]|1.81| |[[:results:exp6|Bortezomib 0.005μM R00 exp6]]|2.44| |[[:results:exp514|Phorbol-12-myristate-13-acetate 0.57μM R08 exp514]]|2.89| No correlation found to any other genes in chemogenomics.
