General description
Cathepsin K is a member of the papain superfamily of cysteine proteinases and plays an important role in osteoclast-mediated bone resorption and collagen degradation. It is primarily expressed by osteoclasts and recent studies also suggest its expression in fibroblasts. Irregularities in cathepsin K activity, either too high or too low, contribute to osteopenic disorders such as osteoporosis and pycnodysostosis. This recombinant enzyme contains a C-terminal His•Tag sequence.

Rationale: Atherosclerosis is characterized by lipid accumulation, plaque formation, and artery stenosis. The pharmacological treatment is a promising therapy for atherosclerosis, but this approach faces major challenges such as targeted drug delivery, controlled release, and non-specific clearance.

Progranulin loss-of-function mutations are linked to frontotemporal lobar degeneration with TDP-43 positive inclusions (FTLD-TDP-Pgrn). Progranulin (PGRN) is an intracellular and secreted pro-protein that is proteolytically cleaved into individual granulin peptides, which are increasingly thought to contribute to FTLD-TDP-Pgrn disease pathophysiology.
