Background Information

Calpastatin (CAST) is an endogenous protein that specifically inhibits the activity of calpains, a family of calcium-dependent proteases involved in numerous cellular processes. The CAST gene encodes calpastatin, which contains multiple calpain-inhibiting domains that bind to the active site of calpain, preventing it from performing its functions. Calpastatin is found in the cytosol and plays a key role in regulating intracellular proteolysis, with malfunctions in the calpain-calpastatin system linked to various diseases, including autoimmune disorders and neurodegenerative conditions.
