The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. There are three inhibitory families in the superfamily, including the type 1 cystatins (stefins), type 2 cystatins and the kininogens. The type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in a variety of human fluids and secr… WebNov 1, 2024 · Cystatins are endogenous, tight-binding and reversible inhibitors of the C1 and C13 families of cysteine peptidases, that are present in tissues and biological fluids [ [1], [2], [3] ].
