Rabbit anti Human Smac/DIABLO antibody recognizes human second mitochondria-derived activator of caspase (Smac), otherwise known as direct IAP-binding protein with low pI (DIABLO) or diablo homolog, mitochondrial. Smac is expressed in a variety of tissues and has been identified as a negative regulator of X-linked inhibitor of apoptosis (XIAP), a member of the IAP (inhibitors of apoptosis proteins) family which blocks cell death by caspase inhibition.

Rabbit anti Human Smac/DIABLO antibody detects Smac as a single band of 21 kDa in a wide range of human cell line lysates. Cross reactivity with rodent cell lines is also observed.
