Overview
Calpain-1 Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction. Forms a heterodimer with a small (regulatory) subunit (CAPNS1). Ubiquitous. Activated by micromolar concentrations of calcium and inhibited by calpastatin. Belongs to the peptidase C2 family. Note: This description may include information from UniProtKB.
Protein type: Motility/polarity/chemotaxis; EC 3.4.22.52; Protease
Cellular Component: membrane; cytoplasm; plasma membrane; cytosol
Molecular Function: protein binding; calcium-dependent cysteine-type endopeptidase activity; calcium ion binding
Biological Process: extracellular matrix disassembly; extracellular matrix organization and biogenesis; receptor catabolic process; positive regulation of cell proliferation; proteolysis
Reference #:  P07384 (UniProtKB)
