Disease

MMP13_HUMAN Defects in MMP13 are the cause of spondyloepimetaphyseal dysplasia Missouri type (SEMD-MO) [MIM:602111. 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. Epimetaphyseal changes improve with age.^[1] Defects in MMP13 are the cause of metaphyseal anadysplasia type 1 (MANDP1) [MIM:602111. 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.^[2]

Function

Publication Abstract from PubMed

Collagenase-3 (MMP-13) is a matrix metalloproteinase involved in human breast cancer pathology and in arthritic processes. The crystal structure of its C-terminal haemopexin-like domain has been solved by molecular replacement and refined to an R-value of 0.195 using data to 2.7 A resolution. This structure reveals a disk-like shape. The chain is folded into a beta-propeller structure of pseudo 4-fold symmetry, with the four propeller blades arranged around a funnel-like tunnel. This central tunnel tube harbours four ions assigned as two calcium and two chloride ions. The C-terminal domain of collagenase-3 has a similar structure to the equivalent domain of gelatinase A and fibroblast collagenase 1; however, its detailed structure and surface charge pattern has a somewhat greater similarity to the latter, in agreement with the subgrouping of MMP-13 with the collagenase subfamily of MMPs. It is proposed that several small structural differences may act together to confer the characteristic binding and cleavage specificities of collagenases for triple-helical substrates, probably in co-operation with a fitting interdomain linker.
