[[http://www.uniprot.org/uniprot/CATK_HUMAN CATK_HUMAN]] 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.
