Gene Information

human ... COL6A3(1293)

General description

COL6A3 (collagen type VI a3) is the a subunit of the fibrotic extracellular matrix protein called collagen. In muscles, it is one of the most abundant collagen expressed. This gene is localized to human chromosome 2q37.

Immunogen

Collagen α-3(VI) chain precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-COL6A3 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

Studies in rodents show that the expression of COL6A3 (collagen type VI α3) is negatively regulated by leptin treatment. Its expression in human adipose tissue is also regulated by leptin, and its expression is decreased in obesity. In humans, its expression is linked with BMI (body mass index) and fat mass. The expression of COL6A3 is similar in patients with obesity and T2DM (type 2 diabtese mellitus), and it regulates adopose tissue macrophage chemotaxis and inflammation. Its expression is also linked with weight gain. The expression of this protein in adipocytes is linked with insulin resistance, which is thought to be dependent on PPAR (peroxisome proliferator-activated receptor) α-mediated adipocyte development.
Mutations in this gene are linked with both mild and server forms of Ullrich congenital muscular dystrophy. Mutations in this gene are also linked with Bethlem myopathy, which is an autosomal dominant disorder.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.
