描述：

Vav3 Antibody检测内源性Vav3总蛋白。该抗体不能与其它内源性的Vav家族成员发生交叉反应。通过人工合成人源Vav3蛋白中间序列周围相应的多肽片段去免疫动物从而制备出多克隆抗体。通过蛋白A和多肽亲和层析纯化抗体。Vav蛋白是属于Rho/Rac小GTPases的鸟苷酸交换因子（guanine nucleotide exchange factor, GEF）Dbl家族。三种已鉴定的哺乳类Vav蛋白(Vav1, Vav2 and Vav3)它们的蛋白表达是不同的。Vav1蛋白仅在造血细胞中表达，并且涉及形成免疫突触。Vav2和Vav3蛋白大量表达。Vav蛋白包含Dbl同源区域，这给予GEF活性，以及蛋白质相互作用区域，该区域允许它们调节肌动蛋白细胞骨架组织的信号通路(1)。磷酸化刺激Rho/Rac的Vav蛋白GEF活性(2,3) 。

Specificity / Sensitivity

Vav3 Antibody detects endogenous levels of total Vav3 protein. The antibody does not cross-react with endogenous levels of other Vav family members.

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the central sequence of human Vav3. Antibodies are purified using protein A and peptide affinity chromatography.

Background

Vav proteins belong to the Dbl family of guanine nucleotide exchange factors (GEFs) for Rho/Rac small GTPases. The three identified mammalian Vav proteins (Vav1, Vav2 and Vav3) differ in their expression. Vav1 is expressed only in hematopoietic cells and is involved in the formation of the immune synapse. Vav2 and Vav3 are more ubiquitously expressed. Vav proteins contain the Dbl homology domain, which confers GEF activity, as well as protein interaction domains that allow them to function in pathways regulating actin cytoskeleton organization (reviewed in 1). Phosphorylation stimulates the GEF activity of Vav protein towards Rho/Rac (2,3).
