General description

GRHL1 (grainyhead-like transcription factor 1) is a transcription factor, which is a member of the GRHL family, which also includes GRHL2 and GRHL3. This gene has a high level of expression in developing mouse skin. This gene is localized to human chromosome 2p25.1.


Grainyhead-like protein 1 homolog recombinant protein epitope signature tag (PrEST)


Anti-GRHL1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). 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

GRHL1 (grainyhead-like transcription factor 1) is a regulator of desmoglein 1 (Dsg1) protein, and thus, controls differentiation of epidermis, and hair anchorage. In mice, inactivation of this gene leads to slow coat growth. It acts as a tumor suppressor in neuroblastoma, where the expression of this gene is repressed by HDAC3 (histone deacetylase) and MYCN (V-Myc avian myelocytomatosis viral oncogene neuroblastoma derived homolog).

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.


Corresponding Antigen APREST70918.

Physical form

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