Calpastatin is a protein that in humans is encoded by the CAST gene.
It is mapped to 5q15.
The protein encoded by this gene is an endogenous calpain (calcium-dependent cysteine protease) inhibitor.
It consists of an N-terminal domain L and four repetitive calpain-inhibition domains (domains 1-4), and it is involved in the proteolysis of amyloid precursor protein.
The calpain/calpastatin system is involved in numerous membrane fusion events, such as neural vesicle exocytosis and platelet and red-cell aggregation.
The encoded protein is also thought to affect the expression levels of genes encoding structural or regulatory proteins.
Alternatively spliced transcript variants encoding different isoforms have been described.
