A disintegrin and metalloproteinase with thrombospondin motifs 5 also known as ADAMTS5 is an enzyme that in humans is encoded by the ADAMTS5gene.[5][6]
Function
ADAMTS5 is a member of the ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) protein family. Members of the family share several distinct protein modules, including a propeptide region, a metalloproteinase domain, a disintegrin-like domain, and a thrombospondin type 1 (TS) motif. Individual members of this family differ in the number of C-terminal TS motifs, and some have unique C-terminal domains. The enzyme encoded by this gene contains two C-terminal TS motifs and functions as aggrecanase to cleave aggrecan, a major proteoglycan of cartilage.[7] ADAMTS5 may also have a role in the pathogenesis of human osteoarthritis.[8]
Animal studies
Genetically modified mice in which the catalytic domain of ADAMTS5 was deleted are resistant to cartilage destruction in an experimental model of osteoarthritis.[9] ADAMTS5 is the major aggrecanase in mouse cartilage in a mouse model of inflammatory arthritis.[10]
