In many cases they are synthesised as part of a larger precursor protein, either as a prepropeptide or as an N-terminal domain associated with an inactive peptidase or zymogen. This domain prevents access of the substrate to the active site. Removal of the N-terminal inhibitor domain either by interaction with a second peptidase or by autocatalytic cleavage activates the zymogen. Other inhibitors interact direct with proteinases using a simple noncovalent lock and key mechanism; while yet others use a conformational change-based trapping mechanism that depends on their structural and thermodynamic properties. The cystatins are cysteine proteinase inhibitors belonging to MEROPS inhibitor family I25, clan IH [, , ]. They mainly inhibit peptidases belonging to peptidase families C1 (papain family) and C13 (legumain family). The cystatin family includes: The Type 1 cystatins, which are intracellular cystatins that are present in the cytosol of many cell types, but can also appear in body fluids at significant concentrations. They are single-chain polypeptides of about 100 residues, which have neither disulphide bonds nor carbohydrate side chains. The Type 2 cystatins, which are mainly extracellular secreted polypeptides synthesised with a 19-28 residue signal peptide. They are broadly distributed and found in most body fluids. The Type 3 cystatins, which are multidomain proteins. The mammalian representatives of this group are the kininogens. There are three different kininogens in mammals: H- (high molecular mass, IPR002395 from INTERPRO) and L- (low molecular mass) kininogen which are found in a number of species, and T-kininogen that is found only in rat. Unclassified cystatins. These are cystatin-like proteins found in a range of organisms: plant phytocystatins, fetuin in mammals, insect cystatins and a puff adder venom cystatin which inhibits metalloproteases of the MEROPS peptidase family M12 (astacin/adamalysin). Also a number of the cystatins-like proteins have been shown to be devoid of inhibitory activity. All true cystatins inhibit cysteine peptidases of the papain family (MEROPS peptidase family C1), and some also inhibit legumain family enzymes (MEROPS peptidase family C13). These peptidases play key roles in physiological processes, such as intracellular protein degradation (cathepsins B, H and L), are pivotal in the remodelling of bone (cathepsin K), and may be important in the control of antigen presentation (cathepsin S, mammalian legumain). Moreover, the activities of such peptidases are increased in pathophysiological conditions, such as cancer metastasis and inflammation. Additionally, such peptidases are essential for several pathogenic parasites and bacteria. Thus in animals cystatins not only have capacity to regulate normal body processes and perhaps cause disease when down-regulated, but in other organisms may also participate in defence against biotic and abiotic stress. ; GO: 0004869 cysteine-type endopeptidase inhibitor activity; PDB: 3L0R_B 2W9P_K 2W9Q_A 3S67_A 3QRD_D 1R4C_G 3GAX_A 1TIJ_B 1G96_A 3NX0_A .... |
