Caspase-1, or interleukin-1ß converting enzyme (ICE/ICEalpha), is a class I cysteine protease, which also includes caspases -4, -5, -11, and -12.
Caspase-1 cleaves inflammatory cytokines such as pro-IL-1beta and interferon-gamma inducing factor (IL-18) into their mature forms.
Like other caspases, caspase-1 is proteolytically activated from a proenzyme to produce a tetramer of its two active subunits, p20 and p10.
Caspase-1 has a large N-terminal pro-domain that contains a caspase recruitment domain (CARD).
Overexpression of caspase-1 can induce apoptosis.
Mice deficient in caspase-1, however, have no overt defects in apoptosis but do have defects in the maturation of pro-IL-1beta and are resistant to endotoxic shock.
At least six caspase-1 isoforms have been identified, including caspase-1 alpha, beta, gamma, delta, epsilon and zeta.
Most caspase-1 isoforms (alpha, beta, gamma and delta) produce products between 30-48kD and induce apoptosis upon over-expression.
Caspase-1 epsilon typically contains only the p10 subunit, does not induce apoptosis and may act as a dominant negative.
The widely expressed zeta isoform of caspase-1 induces apoptosis and lacks 39 N-terminal residues found in the alpha isoform (6).
Activation of caspase-1 occurs through an oligomerization molecular platform designated the "inflammasome" that includes caspase-5, Pycard/Asc, and NALP1.
