Protein

Calpain-2 catalytic subunit

Gene

CAPN2

Organism
Sus scrofa (Pig)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Proteolytically cleaves MYOC at 'Arg-226' (By similarity).By similarity

Catalytic activityi

Broad endopeptidase specificity.

Cofactori

Ca2+By similarityNote: Binds 7 Ca(2+) ions.By similarity

Enzyme regulationi

Activated by 200-1000 micromolar concentrations of calcium and inhibited by calpastatin.
