Function

Thiol protease 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. Involved in the release of thyroid hormone thyroxine (T4) by limited proteolysis of TG/thyroglobulin in the thyroid follicle lumen (PubMed:11082042).

Activity summary

Cathepsin K also known as CTSK is a protease enzyme that belongs to the papain family of cysteine proteases. With a molecular weight of approximately 37 kDa Cathepsin K is mainly expressed in osteoclasts which are cells involved in bone resorption. This enzyme functions by cleaving collagen a vital component of bone extracellular matrix which facilitates bone remodeling and turnover. Known for its collagenolytic activity Cathepsin K is important in processes where breakdown of collagen fibers is required.

Biological function summary

Cathepsin K plays a significant role in bone metabolism. It operates within the osteoclasts where it degrades type I collagen and other matrix proteins essential for normal bone maintenance and repair. Cathepsin K does not function as part of a complex but acts independently in its enzymatic role. It is highly specific to substrates found in the bone matrix differentiating it from other cathepsins like cathepsin L or B that may have broader expression and role.

Pathways

Cathepsin K is an important player in the bone remodeling pathway. This pathway involves a series of coordinated actions between osteoclasts and osteoblasts to maintain bone health. Cathepsin K's activity is tightly regulated within this pathway to ensure proper bone density and structure. It is associated with other proteins such as osteopontin and matrix metalloproteinases which work together to modulate bone turnover. Within the RANK/RANKL pathway Cathepsin K acts as a downstream effector following osteoclast activation by RANKL.

Associated diseases and disorders

Cathepsin K is most notably linked to osteoporosis and pycnodysostosis. Osteoporosis arises due to excessive bone resorption where elevated Cathepsin K activity leads to weakened bone structure increasing fracture risk. Pycnodysostosis is a rare genetic disorder caused by mutations in the gene coding for Cathepsin K resulting in impaired bone resorption and abnormally dense but brittle bones. In these conditions proteins such as RANKL and osteoprotegerin also play critical roles by influencing osteoclast differentiation and activity thereby modulating Cathepsin K's effects.
