Cathepsin V Proteins and Enzymes

Cathepsin V, also known as Cathepsin L2 and Cathepsin U, is a cysteine protease of the papain family. It is expressed as a proenzyme in lysosomes, which can be autocatalytically converted to the mature form at pH 4.0. Cathepsin V is specifically expressed in the thymus, testis, and corneal epithelium.
