A bone disease characterized by moderate to severe metaphyseal changes, mild epiphyseal involvement, rhizomelic shortening of the lower limbs with bowing of the femora and/or tibiae, coxa vara, genu varum and pear-shaped vertebrae in childhood.

Metaphyseal anadysplasia consists of an abnormal bone development characterized by severe skeletal changes that, in contrast with the progressive course of most other skeletal dysplasias, resolve spontaneously with age. Clinical characteristics are evident from the first months of life and include slight shortness of stature and a mild varus deformity of the legs. Patients attain a normal stature in adolescence and show improvement or complete resolution of varus deformity of the legs and rhizomelic micromelia.<ref>PMID:19615667</ref> | ||

| + | The excessive activity of matrix metalloproteinases (MMPs) contributes to pathological processes such as arthritis, tumor growth and metastasis if not balanced by the tissue inhibitors of metalloproteinases (TIMPs). In arthritis, the destruction of fibrillar (type II) collagen is one of the hallmarks, with MMP-1 (collagenase-1) and MMP-13 (collagenase-3) being identified as key players in arthritic cartilage. MMP-13, furthermore, has been found in highly metastatic tumors. We have solved the 2.0 A crystal structure of the complex between the catalytic domain of human MMP-13 (cdMMP-13) and bovine TIMP-2. The overall structure resembles our previously determined MT1-MMP/TIMP-2 complex, in that the wedge-shaped TIMP-2 inserts with its edge into the entire MMP-13 active site cleft. However, the inhibitor is, according to a relative rotation of approximately 20 degrees, oriented differently relative to the proteinase. Upon TIMP binding, the catalytic zinc, the zinc-ligating side chains, the enclosing MMP loop and the S1' wall-forming segment move significantly and in concert relative to the rest of the cognate MMP, and the active site cleft constricts slightly, probably allowing a more favourable interaction between the Cys1(TIMP) alpha-amino group of the inhibitor and the catalytic zinc ion of the enzyme. Thus, this structure supports the view that the central N-terminal TIMP segment essentially defines the relative positioning of the TIMP, while the flanking edge loops determine the relative orientation, depending on the individual target MMP. | ||
