Cathepsins B， C， H， L， S， V， X/Z/P and 1 are cysteine proteases of the papain family. Cathepsin C is also known as DPPI （dipeptidyl-peptidase I）. Cathepsin A is a serine carboxypeptidase and Cathepsin D and E are aspartic proteases. As lysosomal proteases， cathepsins play an important role in protein degradation. Because of their redistribution or increased levels in human and animal tumors， cathepsins may have a role in invasion and metastasis. Cathepsins are synthesized as inactive proenzymes and processed to become mature and active enzymes. Endogenous protein inhibitors， such as cystatins and some serpins， inhibit active enzymes.
