Классификация, регуляция активности, генетический полиморфизм матриксных металлопротеиназ в норме и при патологии

Matrix metalloproteinases (MMPs) are a family of zinc-containing endopeptidases that catalyze the degradation reactions of the extracellular matrix components. In humans, 23 enzymes of this family are known, which are subdivided into 6 groups based on their structure and substrate types: collagenases, gelatinases, stromelysins, matrilizines, MMP membrane type and other MMPs. MMP functions are diverse, and an imbalance of their activity may be one of the etiological factors of various diseases. The review considers classification, regulation of activity and genetic polymorphism of matrix metalloproteinases in health and in various pathological processes in the human body. A list of the most studied polymorphic variants of MMP genes is given, their functional effects are described and the results of associative studies are presented.
