[https://www.uniprot.org/uniprot/CATK_HUMAN CATK_HUMAN] Defects in CTSK are the cause of pycnodysostosis (PKND) [MIM:[https://omim.org/entry/265800 265800]. PKND is an autosomal recessive osteochondrodysplasia characterized by osteosclerosis and short stature.<ref>PMID:8703060</ref> <ref>PMID:9529353</ref> <ref>PMID:10491211</ref> <ref>PMID:10878663</ref>

== Function ==
 +
[https://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.

== Publication Abstract from PubMed ==
 +
Morphing structural features of HTS-derived chemotypes led to the discovery of novel 2-cyano-pyrimidine inhibitors of cathepsin K with good pharmacokinetic profiles, for example, compound 20 showed high catK potency (IC(50)=4nM), &gt;580-fold selectivity over catL and catB, and oral bioavailability in the rat of 52%.
