TWS is an autosomal recessive osteolysis syndrome. It is severe with generalized osteolysis and osteopenia. Subcutaneous nodules are usually absent. Torg-Winchester syndrome has been associated with a number of additional features including coarse face, corneal opacities, patches of thickened, hyperpigmented skin, hypertrichosis and gum hypertrophy. However, these features are not always present and have occasionally been observed in other osteolysis syndromes. Function MMP2_HUMAN Ubiquitinous metalloproteinase that is involved in diverse functions such as remodeling of the vasculature, angiogenesis, tissue repair, tumor invasion, inflammation, and atherosclerotic plaque rupture. As well as degrading extracellular matrix proteins, can also act on several nonmatrix proteins such as big endothelial 1 and beta-type CGRP promoting vasoconstriction. Also cleaves KISS at a Gly-|-Leu bond. Appears to have a role in myocardial cell death pathways. Contributes to myocardial oxidative stress by regulating the activity of GSK3beta. Cleaves GSK3beta in vitro. PEX, the C-terminal non-catalytic fragment of MMP2, posseses anti-angiogenic and anti-tumor properties and inhibits cell migration and cell adhesion to FGF2 and vitronectin. Ligand for integrinv/beta3 on the surface of blood vessels. Isoform 2: Mediates the proteolysis of CHUK/IKKA and initiates a primary innate immune response by inducing mitochondrial-nuclear stress signaling with activation of the pro-inflammatory NF-kappaB, NFAT and IRF transcriptional pathways.

Publication Abstract from PubMed MMP-2 is a member of the matrix metalloproteinase family that has been implicated in tumor cell metastasis and angiogenesis. Here, we describe the solution structure of a catalytic domain of MMP-2 complexed with a hydroxamic acid inhibitor (SC-74020), determined by three-dimensional heteronuclear NMR spectroscopy. The catalytic domain, designated MMP-2C, has a short peptide linker replacing the internal fibronectin-domain insertion and is enzymatically active. Distance geometry-simulated annealing calculations yielded 14 converged structures with atomic root-mean-square deviations (r.m.s.d.) of 1.02 and 1.62 A from the mean coordinate positions for the backbone and for all heavy atoms, respectively, when 11 residues at the N-terminus are excluded. The structure has the same global fold as observed for other MMP catalytic domains and is similar to previously solved crystal structures of MMP-2. Differences observed between the solution and the crystal structures, near the bottom of the S1' specificity loop, appear to be induced by the large inhibitor present in the solution structure. The MMP-2C solution structure is compared with MMP-8 crystal structure bound to the same inhibitor to highlight the differences especially in the S1' specificity loop. The finding provides a structural explanation for the selectivity between MMP-2 and MMP-8 that is achieved by large inhibitors.
