Abstract:
Caspases are central components of the machinery responsible for apoptosis. Recent structural and biochemical studies on procaspases, IAPs, Smac/DIABLO, and apoptosome have revealed a conserved mechanism of caspase activation and inhibition. This article reviews these latest advances and presents our current understanding of caspase regulation during apoptosis.
