Ready-to-use ELISA kits are available for the detection of SMAC3, an alias of the protein, diablo IAP-binding mitochondrial protein. The official gene symbol is DIABLO. The kits can detect several species variants of the protein, including: human, mouse, rat, and other mammalian. The protein, with a mass of 27.1 kDa and length of 239 residues, is reported to be mitochondrial. It may be known by other names, including: SMAC, second mitochondria-derived activator of caspase, direct IAP-binding protein with low pI, diablo-like protein, and diablo homolog mitochondrial.
