| - | + | [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> | |

| - | In common with most other matrix metalloproteinases, gelatinase A has a non-catalytic C-terminal domain that displays sequence homology to haemopexin. Crystals of this domain were used by molecular replacement to solve its molecular structure at 2.6 A resolution, which was refined to an R value of 17.9%. This structure has a disc-like shape, with the chain folded into a beta-propeller structure that has pseudo four-fold symmetry. Although the topology and the side-chain arrangement are very similar to the equivalent domain of fibroblast collagenase, significant differences in surface charge and contouring are observable on 1 side of the gelatinase A disc. This difference might be a factor in allowing the gelatinase A C-terminal domain to bind to natural inhibitor TIMP-2. | ||
