An important part of the apoptotic machinery are the inhibitor of apoptosis protein (IAP) family, regulating caspase activity, cell division or cell survival pathways through binding to their baculovirus AIP repeat (BIR) domains and/or by their ubiquitin-ligase RING zinc finger (RZF) activity. IAPs are also involved in immunity, inflammation, cell cycle and migration[1]. The human IAP family consists 8 members known to date: NAIP (neuronal apoptosis inhibitory protein; BIRC1), cIAP1 and cIAP2 (cellular inhibitor of apoptosis 1 and 2; BIRC2 and BIRC3, respectively), XIAP (X-chromosome binding IAP; BIRC4), survivin (BIRC5), BRUCE (Apollon; BIRC6), livin (BIRC7) and Ts-IAP (testis-specific IAP; BIRC8). Increased IAP expression was found in variety of human cancers, including hematological malignancies, such as leukemias and B-cell lymphomas. A correlation between the progression of those diseases and high levels of survivin or XIAP has been reported. Thus, targeting IAPs with small-molecule inhibitors by their antisense approaches or natural IAP antagonist mimetics, may be an attractive strategy of anti-cancer treatment[2].
