MMPs are a group of enzymes involved in matrix degradation. Of the sixteen members of matrix metalloproteinase family ten exist in soluble form whereas MT-MMPs exist as integral membrane proteins. MT1-MMP, MT2-MMP, MT3-MMP also known as MMP14, MMP15, MMP16 respectively contain a C-terminal transmembrane domain anchoring them to the cell surface. They have an 8 amino acid insert in their catalytic domain. MT1-MMP cleaves progelatinase A (MMP-2) and progelatinase B to their active forms. MT2-MMP plays a minor role in activation of pro-MMP-2 to its active form in breast carcinomas. Coexpression of MT1-MMP and MT2-MMp in advanced stages of breast carcinomas is indicative of possible involvement of MT2-MMP in its metastasis.
