Recombinant Human CASP1

Cat. No.: CASP1-596H
Description: Caspase-1 is the prototypical member of the caspase family of cysteine proteases. Caspase-1 exists in cells as an inactive 45kDa pro-enzyme. The pro-enzyme is matured by proteolysis to yield large (20kDa) and small (10kDa) subunits. The active enzyme is a heterotetramer consisting of two large and two small subunits. To date the mechanism of regulation of caspase-1 activation is complex and poorly understood. In THP-1 cells, a large proportion of the caspase-1 is present in the inactive pro-enzyme form.
Sourse/Host: E. coli.
Formulation: Lyophilized.
Reconstitution: Reconstitute to 1U/µl with PBS containing 15% glycerol.
Specific Activity: ~20'000U/mg protein. One unit is defined as the amount of enzyme that cleaves 1nmol of the caspase substrate YVAD-pNA (pNA:p-nitroanaline) per hour at 37°C in a reaction solution containing 50mM HEPES, pH 7.2, 50mM sodium chloride, 0.1% CHAPS, 10mM EDTA, 5% glycerol and 10mM DTT.
Application: Useful in studying enzyme regulation and inhibitors, determining target substrate, screening caspase inhibitors, or as a positive control in caspase assays. We recommend using 1 unit per assay for analyzing caspase activity.
Storage: For long term storage, -80°C.
Pathways: Amyotrophic lateral sclerosis (ALS); Cytosolic DNA-sensing pathway; NOD-like receptor signaling pathway
