Apoptosis is a genetically programmed, selective process of cell death that occurs during normal cell differentiation and development of multicellular organisms. Inhibitors of apoptosis proteins (IAPs), hILP/XIAP, c-IAP1, c-IAP2, and survivin, suppress apoptosis by preventing procaspase activation and inhibiting mature caspase activity. Smac/DIABLO (second mitochondria-derived activator of caspases) eliminates the inhibitory effect of many IAPs, and has been shown to interact with hILP, c-IAP1, c-IAP2, and survivin. The interaction with hILP occurs through Smac/DIABLO binding to the second and third BIR domains of hILP. Smac/DIABLO protein contains an N-terminal mitochondria targeting sequence (MTS) and a procaspase-3 activation domain. The N-terminal MTS is cleaved after import into the mitochondria, and the activity of the mature Smac/DIABLO is dependent on homodimerization and release from the mitochondria. Overexpression of Smac/DIABLO in HeLa cells increases the sensitivity to UV-mediated apoptosis. Thus, Smac/DIABLO acts as an apoptotic activator through its binding to IAPs and activation of caspases.
