Serpins are a superfamily of proteins with similar structures that were first identified for their protease inhibition activity and are found in all kingdoms of life. The acronym serpin was originally coined because the first serpins to be identified act on chymotrypsin-like serine proteases (serine protease inhibitors). … See more Protease inhibitory activity in blood plasma was first reported in the late 1800s, but it was not until the 1950s that the serpins antithrombin and alpha 1-antitrypsin were isolated, with the subsequent … See more Protease inhibition Approximately two-thirds of human serpins perform extracellular roles, inhibiting proteases … See more All serpins share a common structure (or fold), despite their varied functions. All typically have three β-sheets (named A, B and C) and eight or nine α-helices (named hA–hI). The most … See more When a serpin inhibits a target protease, it forms a permanent complex, which needs to be disposed of. For extracellular serpins, the final serpin-enzyme complexes are rapidly cleared from circulation. One mechanism by which this occurs in mammals … See more Most serpins are protease inhibitors, targeting extracellular, chymotrypsin-like serine proteases. These proteases possess a See more Inhibitory serpins do not inhibit their target proteases by the typical competitive (lock-and-key) mechanism used by most small protease inhibitors (e.g. Kunitz-type inhibitors). … See more Serpins are involved in a wide array of physiological functions, and so mutations in genes encoding them can cause a range of diseases.
