It acts as a central component of the intrinsic pathway of apoptosis. Loss of APAF-1 expression is involved with chemorefractory malignant melanoma and neuronal cell differentiation. Over expression of this gene is related to an undifferentiated state in the testicular germ cell tumor (TGCT) pathway and is involved in carcinogenesis of germ cell tumors. APAF-1, when bound to cytochrome c, may trigger the activation of caspase-3 leading to apoptosis.
