Structural highlights
DiseaseCATK_HUMAN Defects in CTSK are the cause of pycnodysostosis (PKND) [MIM:265800. PKND is an autosomal recessive osteochondrodysplasia characterized by osteosclerosis and short stature.[1] [2] [3] [4] FunctionCATK_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. Publication Abstract from PubMedThe cysteine peptidase cathepsin K is a potent collagenolytic enzyme and a promising target for the treatment of osteoporosis. Here, we characterize its allosteric fine-tuning via a recently identified allosteric site. We show that compound NSC94914 binds this site and acts as a specific partial inhibitor of the collagenolytic activity of cathepsin K. We link the functional differences between NSC94914 and known effectors (compound NSC11345 and glycosaminoglycans) to their different modes of interaction with the site. We characterize the allosteric site by site-directed mutagenesis and show that it is involved in specific regulation of the collagenolytic activity of cathepsin K. An allosteric site enables fine-tuning of cathepsin K by diverse effectors.,Novinec M, Rebernik M, Lenarcic B FEBS Lett. 2016 Nov 17. doi: 10.1002/1873-3468.12495.
