Calpastatin (CAST) is a calpain inhibitor, a calcium-dependent cysteine protease that is widely distributed in higher-order animals. There are different types of calpastatins; examples include the 68-kDa erythrocyte-derived calpastatin and the 107-kDa myocyte-derived calpastatin (as evidenced by SDS-PAGE). Through its inhibition of calpain, calpastatin is believed to play important roles in the regulation of cell proliferation, differentiation, and aging. CAST is also involved in the proteolysis of amyloid precursor protein (APP).
Human Calpastatin Antibody (Monoclonal) (CSL1-5 clone) is raised against recombinant myocyte-derived calpastatin.
- Sensitive and specific measurement of calpastatin levels in cell culture supernatant
