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]. WebApr 1, 2011 · Cystatins are small proteins, typically composed of 100-120 amino acids, which together with similar proteins devoid of inhibitory properties, belong to a cystatin 'superfamily'. Cystatins can do more than just inhibit proteases: two important aspects described here are aggregation properties linked to misfolding diseases and the unique …
