一般說明
VAV1 (vav guanine nucleotide exchange factor 1), a 95kDa protein, is a guanosine diphosphate (GDP)-guanosine triphosphate (GTP) exchange factor of Rac. It is present in almost all hemopoietic cells with a Dbl homology domain, a hallmark of a guanine nucleotide exchange factor (GEF) for Rho-family GTPases.

應用
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.

生化／生理作用
VAV1 (vav guanine nucleotide exchange factor 1) helps to accelerate the exchange of bound GDP for GTP. The activity is controlled by phosphoinositide (PI) 3-kinase substrate through the Ras-dependent mechanism. VAV1 plays the core part in T cell antigen receptor (TCR)-dependent signaling pathways. Deficiency of VAV1 causes defective TCR-induced proliferation and cytokine synthesis in T-cells since VAV1 alters the activation signal of a calcium flux, extracellular signal-regulated kinase (ERK) and the nuclear factor κB (NF-κB) transcription factor. It has also been reported that in phospholipase Cγ1 (PLCγ1) activation, VAVA1 performs via both phosphoinositide-3-kinase (PI3K) dependent and independent pathways.
特點和優勢
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.
