Caspases are a family of cysteine proteases that are key mediators of programmed cell death or apoptosis (1). The precursor form of all caspases is composed of a prodomain, and large and small catalytic subunits. The active forms of caspases are generated by several stimuli including ligand-receptor interactions, growth factor deprivation and inhibitors of cellular functions. All known caspases require cleavage adjacent to aspartates to liberate one large and one small subunit, which associate into a tetramer to form the active enzyme. Caspase-1/ICE (IL-1b converting enzyme) is similar to the cell death gene CED-3 of Caenorhabditilis elegans and regulates multiple proinflammatory cytokines, including interleukin-1b and interferon-gamma-inducing factor.
