Potent inhibitor of cell death. Isoform Bcl-X(L) anti-apoptotic activity is inhibited by association with SIVA isoform 1. Inhibits activation of caspases By similarity. Appears to regulate cell death by blocking the voltage-dependent anion channnel (VDAC) by binding to it and preventing the release of the caspase activator, cytochrome c, from the mitochondrial membrane. The Bcl-X(S) isoform promotes apoptosis.1) Basu A, et. al. ( 2003) Mar 13; 538 (1-3): 41-7Cheng E. H. -Y. et. al. (1996) Nature 379:554-556. Sattler M. et. al. (1997) , Science 275:983-986.
