FunctionPromotes apoptosis by activating caspases in the cytochrome c/Apaf-1/caspase-9 pathway. Acts by opposing the inhibitory activity of inhibitor of apoptosis proteins (IAP).
Tissue specificityUbiquitously expressed with highest expression in testis. Expression is also high in heart, liver, kidney, spleen, prostate and ovary. Low in brain, lung, thymus and peripheral blood leukocytes.
DomainThe mature N-terminus mediates interaction with XIAP.
Cellular localizationMitochondrion. Released into the cytosol when cells undergo apoptosis.
