STRUCTURE OF THE HUMAN COLLAGEN X NC1 TRIMER
Contents |
Overview
Collagen X is expressed specifically in the growth plate of long bones. Its C1q-like C-terminal NC1 domain forms a stable homotrimer and is crucial for collagen X assembly. Mutations in the NC1 domain cause Schmid metaphyseal chondrodysplasia (SMCD). The crystal structure at 2.0 A resolution of the human collagen X NC1 domain reveals an intimate trimeric assembly strengthened by a buried cluster of calcium ions. Three strips of exposed aromatic residues on the surface of NC1 trimer are likely to be involved in the supramolecular assembly of collagen X. Most internal SMCD mutations probably prevent protein folding, whereas mutations of surface residues may affect the collagen X suprastructure in a dominant-negative manner.
Disease
Known diseases associated with this structure: Metaphyseal chondrodysplasia, Schmid type OMIM:[120110], Spondylometaphyseal dysplasia, Japanese type OMIM:[120110]
