Background Apoptosis is a conserved cell suicide program essential for the development and homeostasis of multicellular organisms. Abnormal inhibition of apoptosis is a hallmark of cancer and autoimmune diseases, whereas excessive cell death is found in neurodegenerative disorders such as Alzheimers disease. Executioners of the apoptotic program are cysteine proteases termed caspases that exist as inactive zymogens in living cells and are activated during apoptosis. Active caspases cleave key intracellular protein substrates, resulting in the characteristic morphological changes associated with apoptosis. The release of cytochrome c from the mitochondria triggers the oligomerization of Apaf-1 in an ATP/dATP-dependent manner and induces the autoactivation of caspase-9. Active caspase-9 in turn activates downstream effector caspases including caspase -3, -6 and -7. Given the potentially irreversible cascade triggered by the activation of initiator caspases, it is crucial that activation of caspases be tightly regulated. A number of cellular proteins have been shown to modulate caspase activation and activity. These include members of the Inhibitor of the Apoptosis Protein (IAP) family, such as XIAP, c-IAP-1 and c-IAP-2, which block cell death by inhibiting the activity of the effector caspases -3 and -7 and the initiator caspase-9. Smac/DIABLO (Second Mitochondria-derived Activator of Caspase) is a mitochondrial protein of 27 kDa that is released from mitochondria during apoptosis. Smac/DIABLO promotes caspase activation through binding and neutralizing IAPs.Synonyms: Diablo homolog mitochondrial, Direct IAP-binding protein with low pI, Second mitochondria-derived activator of caspase
Gene ID 56616
NCBI Accession NP_063940
UniProt Q9NR28
Pathways Apoptosis, Caspase Cascade in Apoptosis
Application Notes Western blot: 1: 1000 to 1: 2000 dilution. A 27 kDa band corresponding to humanSmac/DIABLO protein is detected. Detection occurs using HRP Donkey anti-Rabbit IgG andECL. As little as 10 ng of recombinant protein can be detected by ECL. Positive control: Lysates from human HeLa and LNCaP cells.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.
