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]. WebNov 1, 2002 · At the protein level, cystatins S, SA, and SN have about 88% identity ( i.e ., they are very similar), while cystatin D has 60% or less similarity. The structures of cystatins S, SA, and SN have been modeled based on the structure of chicken cystatin ( Bell et al ., 1997) (see Fig. 2 ).
