Cathepsin

Cathepsins are proteases (enzymes that degrades proteins) found in all animals as well as other organisms. The cathepsin family of proteolytic enzymes contains several diverse classes of proteases. Most of the members become activated at the low pH found in lysosomes. The activity of this family lies almost entirely within those organelles. Cathepsins have a vital role in mammalian cellular turnover, e.g. bone resorption. They degrade polypeptides and are distinguished by their substratespecificities. Classification: Cathepsin A, Cathepsin B, Cathepsin C, Cathepsin D, Cathepsin E, Cathepsin F, Cathepsin G, Cathepsin H, Cathepsin K, Cathepsin L1, Cathepsin L2, Cathepsin O, Cathepsin S, Cathepsin W, Cathepsin Z. Most cathepsins are lysosomal and each is involved in cellular metabolism, participating in various events such as peptide biosynthesis and protein degradation. Cathepsins may also cleave some protein precursors, thereby releasing regulatory peptides.
