General description
Rho guanine nucleotide exchange factor 1 (ARHGEF1) is a member of a family of Rho-specific guanine nucleotide exchange factors. It contains a regulator of G protein signaling (rgRGS) domain near its amino-terminus. ARHGEF1 also has a tandem Dbl homology (DH)-Pleckstrin homology (PH) domain.
Immunogen
Rho guanine nucleotide exchange factor 1 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
Rho guanine nucleotide exchange factor 1(ARHGEF1) mediates dissociation of GDP and the binding of GTP. It binds specifically to the nucleotide-depleted state of the substrate. ARHGEF1 acts as a regulator of Rho and plays an important role in the activation of Ras-like proteins. Its amino terminal region helps it to function as an intermediate in the regulation of Rho proteins by G protiens G13 and G12. The GTPase activities of G12 and G13 are stimulated by it. Once G13 is activated by ARHGEF1, it catalyzes the nucleotide exchange on Rho. In arterial smooth muscle cells, it is responsible for angiotensin II-mediated activation of RhoA.
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:
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.

Signaling pathways that link extracellular factors to activation of the monomeric guanosine triphosphatase (GTPase) Rho control cytoskeletal rearrangements and cell growth. Heterotrimeric guanine nucleotide-binding proteins (G proteins) participate in several of these pathways, although their mechanisms are unclear. The GTPase
