EC 22.214.171.124 - Calpain-1
IntEnz Enzyme Nomenclature
calcium-activated neutral protease I
- Broad endopeptidase specificity.
In peptidase family C2. Requires Ca2+ at micromolar concentrations for activity. Cytosolic in animal cells. The active enzyme molecule is a heterodimer in which the large subunit contains the peptidase unit, and the small subunit is also a component of EC 126.96.36.199, calpain-2.
