General Information

General Information Comment Organism
metabolism cathepsin S cleaves cathepsin K (cathepsin cannibalism) which reduces the total elastin- and collagen-degradative activity in the multiple cathepsin system. Cathepsin cannibalism protects type I collagen through a reduction in the amount of highly collagenolytic cathepsin K available due to cathepsin S degradation of cathepsin K Homo sapiens
