additional information | MT1-MMP is inhibited by endogenous inhibitors TIMP-2, -3, and -4, but not by TIMP-1. MT1-MMP on cell surface rapidly turns over by auto-degradation or clathrin-dependent internalization. MT1-MMP inactivated by TIMP-2 avoids auto-degradation, and accumulates on the cell surface, overview | Homo sapiens | |

tissue inhibitor of MMP-2 | MMP-2 activation involves tissue inhibitor of MMP-2, i.e. TIMP-2, as a bridging molecule between MT1-MMP and pro-MMP-2. Thus, net activity of MT1-MMP and MMP-2 is regulated in a complex manner depending on TIMP-2 concentration. MT1-MMP auto-degradation is suppressed in the presence of TIMP-2, and MT1-MMP/TIMP-2 complex accumulates on cell surface. MT1-MMP cannot cleave other direct substrates at the TIMP-2 level that induces efficient pro-MMP-2 processing | Homo sapiens | |

physiological function | an essential role for MT1-MMP in the process of angiogenesis and bone growth. Tetraspanins are attracting attention as binding proteins of MT1-MMP, which regulate subcellular localization and compartmentalization of MT1-MMP and consequent MT1-MMP activities. MT1-MMP plays an essential role in angiogenesis, CD151 may contribute to endothelial homeostasis through the regulation of MT1-MMP. CD9, CD81, and TSPAN12 also associate with cell surface molecules including integrins. Tetraspanin-regulated cell surface localization of MT1-MMP increases the local concentration for focal proteolysis within the pericellular environment and leads to efficient extracellular matrix degradation and MMP-2 activation | Mus musculus |
