遺伝子情報
human ... ARHGEF4(50649)
詳細
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.
免疫原
Rhoグアニンヌクレオチド交換因子4のPrEST(protein epitope signature tag)抗原リコンビナントタンパク質。
アプリケーション
Prestige抗体®は、Human Proteome Resource(HPR)プロジェクト(www.proteinatlas.org)によって開発・実証されたAtlas抗体です。抗体はすべて、数百の正常組織・疾病組織に対する免疫組織染色試験を行っています。これらの染色画像はHuman Protein Atlas(HPA)サイトで[Image Gallery]リンクをクリックするとご覧いただけます。さらに、ほとんどのPrestige抗体はプロテインアレイおよびウェスタンブロッティングの試験を行っています。試験のプロトコールおよびPrestige抗体、HPAに関する情報はsigma.com/prestigeをご覧ください。
生物化学的／生理学的作用
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.
特徴および利点
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
