General annotation (Comments)

Function

Calcium-regulated non-lysosomal thiol-protease which catalyze limited proteolysis of substrates involved in cytoskeletal remodeling and signal transduction By similarity.

Catalytic activity

Broad endopeptidase specificity.

Cofactor

Binds 7 calcium ions By similarity.

Enzyme regulation

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

Subunit structure

Forms a heterodimer with a small (regulatory) subunit (CAPNS1).

Subcellular location

Cytoplasm By similarity. Cell membrane By similarity. Note: Translocates to the plasma membrane upon Ca2+ binding By similarity.

Tissue specificity

Ubiquitous.

Sequence similarities

Belongs to the peptidase C2 family.

Contains 1 calpain catalytic domain.

Contains 3 EF-hand domains.
