Smac, CT, Blocking Peptide (DIABLO, Direct IAP Binding Protein of Low Pi, Second Mitochondrial Activ

The inhibitor of apoptosis proteins (IAPs) regulate programmed cell death by inhibiting members of the caspase family of enzymes. A novel mammalian protein that binds to IAPs and neutralizes the inhibitory effect of IAPs on caspases was recently identi?ed and designated Smac/DIABLO (1,2). Smac/DIABLO is a mitochondrial protein that is released along with cytochrome c during apoptosis and activates cytochrome c/Apaf-1/capase-9 pathway. Analysis of the structural basis of Smac/DIABLO reveals that the N-terminal amino acids are required for binding of Smac/DIABLO to IAPs and activation of caspases (3-6). Smac/DIABLO is expressed in a variety of human and mouse tissues (1,2). Peptide (SDEGADQEEEAYLRED) corresponding to amino acids 222 to 237 of murine Smac/DIABLO (2). , Applications: Suitable for use in ELISA and Western Blot. Other applications not tested., , Storage and Stability: Lyophilized powder may be stored at -20°C. Reconstitute to nominal volume by adding sterile 25% glycerol and store at -20°C.
