CC -!- FUNCTION: Calcium-regulated non-lysosomal thiol-protease which catalyze
CC limited proteolysis of substrates involved in cytoskeletal remodeling
CC and signal transduction. {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Broad endopeptidase specificity.; EC=3.4.22.53;
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108; Evidence={ECO:0000250};
CC Note=Binds 7 Ca(2+) ions. {ECO:0000250};
CC -!- ACTIVITY REGULATION: Activated by 200-1000 micromolar concentrations of
CC calcium and inhibited by calpastatin.
CC -!- SUBUNIT: Forms a heterodimer with a small (regulatory) subunit
CC (CAPNS1).
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Cell membrane
CC {ECO:0000250}. Note=Translocates to the plasma membrane upon Ca(2+)
CC binding. {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Ubiquitous.
CC -!- SIMILARITY: Belongs to the peptidase C2 family. {ECO:0000305}.
