Cystatin-8 is a protein that in humans is encoded by the CST8 gene.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.
