Gene Information
human ... ARHGEF4(50649)
General description
The gene rho guanine nucleotide exchange factor-4 (ARHGEF4) is mapped to human chromosome 2q22. ARHGEF4 transcript has been detected in brain, skeletal muscle and testis.
Immunogen
Rho guanine nucleotide exchange factor 4 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-4 (ARHGEF4) is involved in hepatocyte growth factor mediated endothelial barrier enhancement and anti-inflammatory effects. Adenomatous polyposis coli protein activates ARHGEF4. The activated ARHGEF4 stimulates the GTPase CDC42 (cell division control 42), which leads to decreased cell-cell adherence and enhanced cell migration. Overexpression of ARHGEF4 induces and maintains proliferation of haematopoietic progenitor cells.
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.

Adenomatous polyposis coli (APC) regulates cell-cell adhesion and cell migration through activating the APC-stimulated guanine nucleotide-exchange factor (GEF; Asef), which is usually autoinhibited through the binding between its Src homology 3 (SH3) and Dbl homology (DH) domains. The APC-activated Asef
