3.4.22.38
Cathepsin K.
based on mapping to UniProt P43236
Broad proteolytic activity. With small-molecule substrates and inhibitors, the major determinant of specificity is P2, which is preferably Leu, Met > Phe, and not Arg.
-!- Prominently expressed in mammalian osteoclasts, and believed to play a role in bone resorption. -!- Belongs to peptidase family C1.
