Protein: Calpastatin (A0A6Q8PFF6)
Organism: Homo sapiens (Human)
Function: Specific inhibition of calpain (calcium-dependent cysteine protease). Plays a key role in postmortem tenderization of meat and have been proposed to be involved in muscle protein degradation in living tissue
InterPro domains:
- IPR001259: Proteinase inhibitor I27, calpastatin (repeat) [45-534]
- IPR026998: Calpastatin (family) [263-608]
