Anti-RAPGEF1 antibody produced in rabbit，100UL，HPA006426-100UL，Sigma

General description

RAPGEF1 (Rap guanine nucleotide exchange factor 1) is a guanine nucleotide exchange factor, and the gene is localized to human chromosome 9q34.3. This protein has a ubiquitous expression pattern, and resides as a complex with Crk (CT10 regulator of kinase) family of proteins in the cytoplasm.
Rap guanine nucleotide exchange factor 1 is a protein encoded by the RAPGEF1 gene in humans. It is referred to as C3G and GRF2. It is mapped to human chromosome 9q34.3. It releases GDP from the inactive Rap1 protein. It may facilitate activation by binding to GTP. This protein acts as an exchange factor for Ras family of small GTPases.

Immunogen

Rap 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

RAPGEF1 (Rap guanine nucleotide exchange factor 1) is responsible for the exchange of GDP with GTP from Rap1 protein, thus, activating it. Rap1 (Ras-related protein 1) protein in turn is involved in processes such as, differentiation, proliferation and apoptosis. It is up-regulated in small cell lung cancers, where it leads to aberrations in CRK (CT10 regulator of kinase)-Rap1 signaling pathway, and thus, acts as an oncogene. This protein participates in multiple signaling cascades, such as the growth factor-mediated and GPCR (G-protein coupled receptor)-mediated. It participates in T-cell and B-cell activation and cell adhesion. Its interaction with Rap1 results in secretion of MMP (matrix metalloproteinase)-2 and MMP-9 in serous ovarian cancer. This protein is thus, involved in metastasis of epithelial ovarian cancer (EOC).

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
