Matrix metalloproteinases (MMPs), also known as matrixins are endoproteinases that degrading protein components of the extracellular matrix (ECM), cause its restoration and reconstruction. In this way, retain the appropriate structure of the ECM and basement membrane during both: physiological processes and pathological conditions. Changes in the structure of the ECM are accompanied by physiological processes such as embryogenesis, angiogenesis, apoptosis, and development and rebuilding of connective tissue. Under physiological conditions, the activity of MMPs is regulated at the transcriptional level, activation of proMMP precursor zymogens and interactions with endogenous inhibitors (tissue inhibitors of metalloproteinases, TIMPs). The imbalance in the system of MMPs/TIMPs induces the development of many diseases, including cancer, fibrosis, arthritis, cardiovascular diseases, neurological and autoimmune disorders. The publication describes the types of metalloproteinases, their structure, function and regulation of activity and endogenous inhibitors of MMPs.
基质金属蛋白酶(MMPs),也被称为基质溶素,是一类能降解细胞外基质(ECM)蛋白质成分的内肽酶,可导致其修复与重建。通过这种方式,在生理过程和病理状态下均能维持ECM和基底膜的适当结构。ECM结构的变化伴随着诸如胚胎发生、血管生成、细胞凋亡以及结缔组织的发育与重建等生理过程。在生理条件下,MMPs的活性在转录水平、前MMP前体酶原的激活以及与内源性抑制剂(金属蛋白酶组织抑制剂,TIMPs)的相互作用方面受到调控。MMPs/TIMPs系统的失衡会诱发多种疾病的发生,包括癌症、纤维化、关节炎、心血管疾病、神经和自身免疫性疾病。该出版物描述了金属蛋白酶的类型、其结构、功能以及活性调节和MMPs的内源性抑制剂。
