== Disease ==
[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 ==
A novel dioxo-triazine series of cathepsin K inhibitors was identified from HTS. A rapid exploratory programme led to the discovery of potent and selective cathepsin K inhibitors, typified by compound 24 which displayed IC(50) values of 17nM against catK and &gt;10,000nM in catL, catB and catS assays.
