General description

The gene GREB1 (growth regulation by estrogen in breast cancer 1) is mapped to human chromosome 2p25.

Immunogen

growth regulation by estrogen in breast cancer 1 recombinant protein epitope signature tag (PrEST)

Application

Anti-GREB1 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

GREB1 (growth regulation by estrogen in breast cancer 1) is regulated by estrogen and plays an important role in breast cancer. It controls 17β-estradiol-stimulated breast cancer cell growth. Additionally, it acts as a cofactor for ESR1 (estrogen receptor α)-associated transcription in the cancer cells. It is also linked with ovarian tumor progression. Changes in the expression of it are associated with risk of endometriosis.

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.

Physical form

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