Function

[BIRC7_HUMAN] Apoptotic regulator capable of exerting proapoptotic and anti-apoptotic activities and plays crucial roles in apoptosis, cell proliferation, and cell cycle control. Its anti-apoptotic activity is mediated through the inhibition of CASP3, CASP7 and CASP9, as well as by its E3 ubiquitin-protein ligase activity. As it is a weak caspase inhibitor, its anti-apoptotic activity is thought to be due to its ability to ubiquitinate DIABLO/SMAC targeting it for degradation thereby promoting cell survival. May contribute to caspase inhibition, by blocking the ability of DIABLO/SMAC to disrupt XIAP/BIRC4-caspase interactions. Protects against apoptosis induced by TNF or by chemical agents such as adriamycin, etoposide or staurosporine. Suppression of apoptosis is mediated by activation of MAPK8/JNK1, and possibly also of MAPK9/JNK2. This activation depends on TAB1 and NR2C2/TAK1. In vitro, inhibits CASP3 and proteolytic activation of pro-CASP9. Isoform 1 blocks staurosporine-induced apoptosis. Isoform 2 blocks etoposide-induced apoptosis. Isoform 2 protects against natural killer (NK) cell killing whereas isoform 1 augments killing.^[1] ^[2] ^[3] ^[4]

Publication Abstract from PubMed

A series of IAP antagonists based on an azabicyclooctane scaffold was designed and synthesized. The most potent of these compounds, 14b, binds to the XIAP BIR3 domain, the BIR domain of ML-IAP, and the BIR3 domain of c-IAP1 with K(i) values of 140, 38, and 33 nM, respectively. These compounds promote degradation of c-IAP1, activate caspases, and lead to decreased viability of breast cancer cells without affecting normal mammary epithelial cells. Finally, compound 14b inhibits tumor growth when dosed orally in a breast cancer xenograft model.
