Specificity / Sensitivity

Phospho-VEGF Receptor 2 (Tyr1175) (D5B11) Rabbit mAb detects endogenous levels of VEGF receptor 2 protein only when phosphorylated at Tyr1175. This antibody may cross-react with other tyrosine-phosphorylated receptor tyrosine kinases, including FLT3.

Background

Vascular endothelial growth factor receptor 2 (VEGFR2, KDR, Flk-1) is a major receptor for VEGF-induced signaling in endothelial cells. Upon ligand binding, VEGFR2 undergoes autophosphorylation and becomes activated (1). Major autophosphorylation sites of VEGFR2 are located in the kinase insert domain (Tyr951/996) and in the tyrosine kinase catalytic domain (Tyr1054/1059) (2). Activation of the receptor leads to rapid recruitment of adaptor proteins, including Shc, Grb2, PI-3 kinase, Nck and the protein tyrosine phosphatases SHP-1 and SHP-2 (3). The phosphorylation of Tyr1212 provides a docking site for Grb2 binding and phospho-Tyr1175 binds with the p85 subunit of PI-3 kinase and PLCγ, as well as Shb (1,4,5). Signaling from VEGFR2 is necessary for the execution of VEGF-stimulated proliferation, chemotaxis and sprouting, as well as survival of cultured endothelial cells in vitro and angiogenesis in vivo (6-8).

血管内皮生长因子受体2 (VEGFR2, KDR, Flk-1)是内皮细胞上VEGF诱导信号时的一个主要受体。和配体结合之后,VEGFR2发生自磷酸化并被活化(1)。VEGFR2 主要的自磷酸化受体位于激酶插入区 (Tyr951/996)和酪氨酸激酶催化区(Tyr1054/1059) (2)。受体的激活会导致对包括Shc, Grb2, PI3K激酶, Nck 和蛋白酪氨酸磷酸化酶SHP-1 和 SHP-2接头蛋白的快速招募(3)。Tyr1212的磷酸化为Grb2提供了结合位点而且磷酸化的Tyr1175能结合PI3K激酶的p85 亚基以及PLCγ和 Shb (1,4,5)。VEGFR2信号传导对于实现VEGF刺激引起的增殖、趋化和发芽,以及体外培养的内皮细胞的增殖和体内血管的发生是必需的(6-8)。
