Suppresses apoptosis in a variety of cell systems including factor-dependent lymphohatopoietic and neural cells. Regulates cell death by controlling the mitochondrial membrane permeability. Appears to function in a feedback loop system with caspases. Inhibits caspase activity either by preventing the release of cytochrome c from the mitochondria and/or by binding to the apoptosis-activating factor (APAF-1). Source: Partial recombinant protein corresponding to aa5-205 from mouse Bcl2, fused to His-Tag at N-terminal, expressed in E. coli.
