In the presence of an appropriate stimulus, accelerates programmed cell death by binding to, and antagonizing the anti- apoptotic action of BCL2 or its adenovirus homolog E1B 19k protein. Low micromolar levels of zinc ions inhibit the promotion of apoptosis. Interacts with BCL2A1. Homodimer. Formation of the homodimer is zinc-dependent. Forms heterodimers with BCL2, E1B 19k protein, and BCL2L1 isoform Bcl-X(L). Interacts with myxoma virus protein M11L. Expressed in a wide variety of tissues, with highest levels in the heart and skeletal muscle. Belongs to the Bcl-2 family. Note: This description may include information from UniProtKB.
