The regulation of MMP-2 activity occurs at many levels, of which regulation through TIMP-2 and its cell surface receptor, MT1-MMP (MMP14) is critically decisive. At higher levels of TIMP-2, MT1-MMP forms a ternary complex with MMP-2 through, leaving no free MT1-MMP receptors, thereby inhibiting the activation of pro-MMP-2 by MT1-MMP. But at lower levels of TIMP-2, due to availability of free MT1-MMP, MT1-MMP mediated activation of MMP-2 is observed. Further data also indicates that expression of TIMP-2, MMP-2 and MT1-MMP (MMP-14) is co-regulated transcriptionally, demonstrating an intricate network of regulation. Pro-MMP-2 activation is also seen by complex signaling induced by ECM proteins like osteopontin, various cytokines for example IL-8 in endothelial cells and other factors.
