Human A Disintegrin And Metalloproteinase With Thrombospondin 4 (ADAMTS4) Protein

Background

ADAMTS4, also known as A Disintegrin And Metalloproteinase with Thrombospondin Motifs 4, is a member of the ADAMTS protein family. ADAMTS4 contains multiple domains, including a metalloproteinase domain responsible for its enzymatic activity, as well as thrombospondin type-1 (TSP-1) motifs. ADAMTS4 is primarily known for its role in extracellular matrix remodeling, particularly in the breakdown of aggrecan, a large proteoglycan found in cartilage. ADAMTS4 cleaves aggrecan at specific sites, leading to the degradation of cartilage matrix and contributing to the pathogenesis of osteoarthritis and other joint-related disorders. It is one of the key enzymes involved in cartilage degradation in osteoarthritis.ADAMTS4 has been implicated in various diseases, particularly osteoarthritis. Elevated levels of ADAMTS4 expression have been observed in osteoarthritic cartilage, synovial fluid, and serum, suggesting its involvement in the disease process. Inhibition of ADAMTS4 activity has been explored as a potential therapeutic strategy for osteoarthritis to prevent cartilage degradation.Research on ADAMTS4 has implications for understanding the pathogenesis of osteoarthritis and other joint-related disorders. Targeting ADAMTS4 activity or expression may represent a promising therapeutic approach for these conditions. Additionally, further research into the regulation and function of ADAMTS4 may provide insights into its roles in normal physiology and other diseases.
