+== Disease ==
+[https://www.uniprot.org/uniprot/MMP2_HUMAN MMP2_HUMAN] Defects in MMP2 are the cause of Torg-Winchester syndrome (TWS) [MIM:[https://omim.org/entry/259600 259600]; also known as multicentric osteolysis nodulosis and arthropathy (MONA). 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.<ref>PMID:11431697</ref> <ref>PMID:15691365</ref> <ref>PMID:16542393</ref>
+== Function ==
+[https://www.uniprot.org/uniprot/MMP2_HUMAN 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.<ref>PMID:9476898</ref> <ref>PMID:10559137</ref> <ref>PMID:11029402</ref> <ref>PMID:11751392</ref> <ref>PMID:11710594</ref> <ref>PMID:19493954</ref> <ref>PMID:22509276</ref>   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.

+== Publication Abstract from PubMed ==
+Human matrix metalloproteinase-2 (MMP-2) contains three in-tandem fibronectin type II (FII) repeats that bind gelatin. Here, we report the NMR solution structure of the first FII module of MMP-2 (col-1). The latter is described as a characteristic, globular FII fold containing two beta-sheets, a stretch of 3(1)-helix, a turn of alpha-helix, and an exposed hydrophobic surface lined with aromatic residues. We show that col-1 binds (Pro-Pro-Gly)6, a mimic of gelatin, with a Ka of approx. 0.42 mm(-1), and that its binding site involves a number of aromatic residues as well as Arg34, as previously found for the second and third homologous repeats. Moreover, the affinity of the in-tandem col-1+2 construct (col-12) toward the longer ligand (Pro-Pro-Gly)12 is twice that for (Pro-Pro-Gly)6, as expected from mass action. A detailed structural comparison between FII and kringle domains indicates that four main conformational features are shared: two antiparallel beta-sheets, a central 3(1)-helix, and the quasiperpendicular orientation of the two proximal Cys-Cys bonds. Structure superposition by optimizing overlap of cystine bridge areas results in close juxtaposition of their main beta-sheets and 31-helices, and reveals that the gelatin binding site of FII modules falls at similar locations and exhibits almost identical topological features to those of the lysine binding site of kringle domains. Thus, despite the minor (&lt;15%) consensus sequence relating FII modules to kringles, there is a strong folding and binding site structural homology between the two domains, enforced by key common conformational determinants.
