Calpain-2.
based on mapping to UniProt P17655
Broad endopeptidase specificity.
-!- 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 3.4.22.52. -!- Belongs to peptidase family C2. -!- Formerly EC 3.4.22.17 and EC 3.4.24.5.
