Anti-Cathepsin K/CTSK Antibody Picoband® (FITC Conjugate)

Cathepsin K, abbreviated?CTSK, is an?enzyme?that in humans is encoded by the?CTSK?gene. It is mapped to 1q21. The protein encoded by this gene is a lysosomal?cysteine protease?involved in bone remodeling and resorption. And this protein, which is a member of the peptidase C1 protein family, is expressed predominantly in?osteoclasts. Additionally, the enzyme's ability to catabolize?elastin,?collagen, and?gelatin?allow it to break down?bone?and cartilage. This catabolic activity is also partially responsible for the loss of lung elasticity and recoil inemphysema. Cathepsin K?inhibitors, such as?odanacatib, show great potential in the treatment of?osteoporosis. Cathepsin K is degraded by Cathepsin S, called Controlled Cathepsin Cannibalism.

E. coli-derived human Cathepsin K recombinant protein (Position: A115-M329). Human Cathepsin K shares 86.9% and 88.8% amino acid (aa) sequence identity with mouse and rat Cathepsin K, respectively.

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.
