* Information From OMIM

Description: Calpain (calcium-dependent protease; EC 3.4.22.17) is an intracellular protease that requires calcium for its catalytic activity. Two isozymes, calpain I (mu-calpain) and calpain II (m-calpain), with different calcium requirements, have been identified. Both are heterodimers composed of L (large, catalytic, 80 kD) and S (small, regulatory, 30 kD) subunits. The isozymes share an identical S subunit (CAPNS1; 114170), with the differences arising from the L subunits, L1 (CAPN1) and L2 (CAPN2; OMIM:114230).
