Caspase proteins are a family of cysteine proteases that are key mediators of programmed cell death or apoptosis (1). The precursor form of all caspase proteins 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 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.

Western blot analysis of Caspase-1 using anti-Caspase-1 monoclonal antibody (CM4891) at 1:1000 to probe blots containing human HeLa (A) and mouse NIH3T3 (B) lysates.

Clone 14F468 was generated from a synthetic peptide corresponding to amino acids 371-390 (RKVRFSFEQPDGRAQMPTTE) in the C-terminal region of human caspase-1. This sequence has high homology to the conserved region in mouse and rat caspase-1.
