Cystatin superfamily
WebThe cystatin superfamily of cysteine protease inhibitors is composed of distinct families of intracellular stefins and secreted true cystatins. FhCyLS-2 from F. hepatica is an unusual member of the superfamily, where our sequence and 3D structure analyses in this study revealed that it combines characteristics of both families. The protein ... WebThe 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. ...

WebThe cystatin superfamily (stefins, cystatins and kininogens) is the classical inhibitors of papain-like cysteine proteinases. Cystatin C is the most potent endogenous inhibitor of CTSS. Cystatin is constitutively expressed by most cells and contains a signal peptide enabling its secretion to the extracellular milieu [70]. WebWe have examined the amino acid sequences of a number of proteins that have been suggested to be related to chicken cystatin, a protein from chicken egg white that inhibits cysteine proteinases.
