The Inhibitors of apoptosis (IAP) are a family of functionally and structurally related proteins. The human family has eight members: NAIP (BIRC1), BIRC2 (cIAPl), BIRC3 (cIAP2), XIAP (BIRC4), BIRC5 (survivin), BIRC6 (apollon), BIRC7 (livin) and BIRC8. All members of the family contain 1-3 copies of a 70-80 amino acid motif known as BIR (baculovirus IAP repeat). The IAPs have garnered interest as drug targets with antineoplastic [1,9] and immunomodulatory  potential. Small molecule, antagonistic, peptide mimetics have been described [5-6,8].
