ab49892 recognizes all three forms of Cathepsin K (but does not see the 288 amino acid form as well as the other two forms, due to a partial deletion of the sequence).
We have a range of domain specific antibodies for this target. For a full list please see all Cathepsin K antibodies.
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.
Predominantly expressed in osteclasts (bones).
Involvement in disease
Defects in CTSK are the cause of pycnodysostosis (PKND) [MIM:265800]. PKND is an autosomal recessive osteochondrodysplasia characterized by osteosclerosis and short stature.
