Product details:
The Human ADAMTS4 Enzyme-Linked Immunosorbent Assay (ELISA) kit (ab213753) is designed for the quantitative measurement of Human ADAMTS4 in cell culture supernatants, cell lysates, serum and plasma (heparin, EDTA).
The ELISA kit is based on standard sandwich enzyme-linked immunosorbent assay technology. A monoclonal antibody from mouse specific for ADAMTS4 has been pre-coated onto 96-well plates. Standards (Expression system for standard: CHO; Immunogen sequence: F213-C685) and test samples are added to the wells, a biotinylated detection polyclonal antibody from goat specific for ADAMTS4 is added subsequently and then followed by washing with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the Human ADAMTS4 amount of sample captured in plate.
ADAMTS4, a disintegrin and metalloproteinase with thrombospondin motifs 4 is an enzyme that in humans is encoded by the ADAMTS4 gene. ADAMTS4 is a member of the large ADAMTS family of zinc-dependent proteases. The human ADAMTS4 gene is mapped to chromosome 1 by somatic cell hybrid analysis. The enzyme encoded by this gene lacks a C-terminal TS motif. It is responsible for the degradation of aggrecan, a major proteoglycan of cartilage, and brevican, a brain-specific extracellular matrix protein. The cleavage of aggrecan and brevican suggests key roles of this enzyme in arthritic disease and in the central nervous system, potentially, in the progression of glioma.

ADAMTS4 also known as aggrecanase-1 is a protein responsible for extracellular matrix degradation. It weighs approximately 90 kDa. This metalloproteinase is expressed in various tissues including cartilage and synovial tissue. It cleaves aggrecan a core protein of the proteoglycan into fragments impacting the integrity and function of the cartilage matrix. It is secreted as a latent enzyme and undergoes activation in the extracellular space.
Biological function summary
ADAMTS4 influences tissue remodeling through the breakdown of cartilage. It contributes to the disassembly of aggrecan and other matrix components influencing extracellular matrix turnover. As part of a group of similar enzymes it plays a role in proteolytic processes important for normal tissue maintenance and repair. Its actions affect the balance between matrix synthesis and degradation which is important for maintaining tissue homeostasis.
Pathways
ADAMTS4 participates in pathways such as the inflammation-related cytokine signaling and the degradation of the extracellular matrix. This protein interacts closely with ADAMTS5 contributing to matrix degradation and modulation of inflammatory processes. In these pathways the balanced activity of ADAMTS4 is essential for proper cartilage function and the resolution of inflammation in tissues.
ADAMTS4 is notably linked to osteoarthritis and rheumatoid arthritis. These conditions involve excessive cartilage breakdown where ADAMTS4 and ADAMTS5 contribute significantly to disease progression through aggrecan degradation. Understanding the activity and regulation of ADAMTS4 offers insights into potential therapeutic strategies for managing cartilage degeneration and inflammatory joint diseases.
