Calcium Binding
catalytic Activity CATALYTIC ACTIVITY: Reaction=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.; EC=3.4.22.38; Evidence={ECO:0000250|UniProtKB:P43235};
DNA Binding
EC Number 3.4.22.38
Enzyme Function FUNCTION: Closely involved in osteoclastic bone resorption and may participate partially in the disorder of bone remodeling. Displays potent endoprotease activity against fibrinogen at acid pH. May play an important role in extracellular matrix degradation (By similarity). {ECO:0000250|UniProtKB:P43235}.
