Survivin, a member of the IAP family, is encoded by the BIRC5 (baculoviral IAP repeat-containing 5) gene located at 17q25, and it plays a role in cell division by inhibiting apoptosis and regulating the process of mitosis in embryonic cells during embryogenesis and in cancer cells during tumorigenesis and tumor metastasis [19]. Here, BIRC5 is linked to cancer.
