Cathepsin K (Cat K) is a member of the Cathepsin family and is found in a wide range of tissues. Cat K is involved in the terminal catabolism and recycling of endocytosed proteins, as well as specific cellular processes and a wide range of diseases. It is predominantly expressed in osteoclasts and has potent collagenase activity. Based on its particular structure and biological functions, Cat K inhibitors with precise targeting and good penetration are potential therapeutic approaches for related diseases. In this paper, we introduce the structure and biological functions of Cat K and focus on Cat K inhibitors with therapeutic potential for human diseases.

Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
