The cystatins are a family of cysteine protease inhibitors which share a sequence homology and a common tertiary structure of an alpha helix lying on top of an anti-parallel beta sheet. The family is subdivided as described below. Cystatins show similarity to fetuins, kininogens, histidine-rich glycoproteins and … See more The cystatin family includes: • The Type 1 cystatins, which are intracellular and are present in the cytosol of many cell types, but can also appear in body fluids at significant concentrations.

WebCystatins are characterized by three conserved domains forming the inhibitory sites of interaction with proteases: an N-terminal glycine, a glutamine-X-valine-X-glycine motif … 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]. WebType 1 cystatins (stefins) are single domain proteins of about 100 amino acids, having no disulfide bonds, while type 2 cystatins are somewhat longer, about 120 amino acids, and have two internal disulfide bonds, kininogens are high molecular mass and multidomain glycoproteins ( Pavlova et al., 2000 ). spring fest in the burg
