cathepsin K

Collagen-cleaving protease

Cathepsin K is an enzyme that breaks down proteins, particularly collagen in bone tissue.

It plays a central role in bone resorption—the process by which osteoclasts dissolve bone material.

The enzyme is a target for osteoporosis drugs, since inhibiting it can slow bone loss.

Cathepsin K also appears in other tissues where collagen degradation occurs.
