ANTI-GRK6 (C005B-204911)

General description

The gene GRK6 (G protein-coupled receptor kinase 6) is mapped to human chromosome 5q35. GRK6 transcript is expressed in various tissues including heart, brain, placenta, lung, liver, kidney, pancreas and skeletal muscle. It is a membrane associated protein.

Immunogen

G protein-coupled receptor kinase 6 recombinant protein epitope signature tag (PrEST)

Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

Biochem/physiol Actions

GRKs (G protein-coupled receptor kinases) generally phosphorylate agonist-activated G-protein coupled receptors and cause desensitization of these receptors. GRK6 phosphorylate chemokine receptor CXCR4 (C-X-C chemokine receptor type 4) and negatively regulate its signaling. GRK6 binds and phosphorylates low density lipoprotein receptor-related proteins-6 (LRP6), thereby resulting in LRP6 activation and Wnt/LRP6 signaling. GRK6 levels are reduced in elderly patients with schizophrenia. It is up-regulated in hepatocellular carcinoma.

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.

Linkage

Corresponding Antigen APREST73516.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
