MMP15 (MT2-MMP) was identified as a membrane-type MMP with a transmembrane domain at the C terminus; it localizes to the cell surface and activates pro-gelatinase A (pro-MMP-2), processing the 68-kDa form through a 64-kDa intermediate to a 62-kDa active form upon transfection into cells. |

MT2-MMP activates MMP-2 via a TIMP-2-independent pathway; activation requires MMP-2 hemopexin C-domain-dependent cell surface association of MMP-2 with MT2-MMP, and proceeds through the 68-kDa intermediate without requiring TIMP-2 or concanavalin A. |

The TIMP-2-independence of MT2-MMP-mediated MMP-2 activation is determined by contributions of both the MT2-MMP catalytic domain (higher propensity to initiate prodomain cleavage without TIMP-2) and the hemopexin C domain (required for the second activation cleavage); MT2-MMP also exhibits weak collagenase activity, and activation is enhanced in type I collagen gels. |

MT2-MMP (MMP15) cooperates with MT1-MMP downstream of Snail1 to drive basement membrane degradation, angiogenesis, and cancer cell intravasation in vivo; siRNA silencing of MT2-MMP completely ablates Snail1-triggered BM invasion and angiogenesis, and these activities cannot be mimicked by secreted MMPs. |

MMP15 (mmp15) is a direct transcriptional target of Snai1 during endothelial-to-mesenchymal transformation (EMT) in endocardial cushion development; Snai1 overexpression induces mmp15 expression and mesenchymal cell migration, while catalytically active MMP15 promotes cell motility (but not transformation), and MMP15 activity rescues migration defects caused by Snai1 knockdown. |

MT2-MMP (MMP15) proteolytically cleaves E-cadherin, generating an 80-kDa N-terminal ectodomain fragment, leading to EMT; catalytically inactive E260A mutant MT2-MMP fails to produce E-cadherin cleavage, restore mesenchymal morphology, or enhance invasion, demonstrating that proteolytic activity is required. |

MT2-MMP (MMP15) localizes to the apical domain of polarized epithelial cells where its cytosolic tail interacts with ZO-1; it cleaves E-cadherin at apical junctions, disrupting E-cadherin-mediated cell quiescence, relaxing cortical tension, promoting cell extrusion, and re-sorting Src kinase activity to junctional complexes to drive proliferation. |

MT2-MMP (MMP15) is a novel hypoxia-responsive gene; HIF-1α directly binds to a specific hypoxia-responsive element (HRE1) in the MT2-MMP promoter to transcriptionally upregulate MT2-MMP under hypoxia, conferring resistance to apoptosis and increased invasiveness. |
