Calpain-3.
based on mapping to UniProt P20807
Broad endopeptidase activity.
-!- Activated by autoproteolytic cleavage of insertion sequence 1 (IS1), which allows substrates and inhibitors gain access to the active site. -!- Substrates include the protein itself and connectin/titin. -!- Belongs to peptidase family C2.
