a antiapoptotic member of the Bcl-2 family. Regulates cell death by controlling the mitochondrial membrane permeability. 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). Phosphorylation by JNKs may increase its antiapoptotic functions. Note: This description may include information from UniProtKB.
