Rabbit polyclonal to SmacSecond mitochondrial activator of caspases or Smac / Diablo can promote apoptosis by relieving the inhibition of caspases by the IAPs (1&2). The other mitochondrial activator of apoptosis is cytochrome c (1). Smac / Diablo export from the mitochondria into the cytosol can be triggered by cytotoxic drugs, DNA damage, and the ligation of FAS (CD95) death receptor (3). Once in the cytosol Smac / Diablo eliminates the inhibitory effects of the IAPs through and amino terminal interaction with the IAP proteins, and thus allow the activation of caspases (2&4). The interaction of Smac / Diablo's amino terminus with the IAP proteins has been localized to their BIR domains, for XIAP the key domain is BIR3 (4&5). |
