Monoclonal Rabbit Supernatant E B IH
Vascular endothelial growth factor receptor 2 (VEGFR-2, KDR, Flk-1) is a major receptor transducing VEGF-induced signaling in endothelial cells. Upon ligand binding, VEGFR-2 undergoes autophosphorylation and becomes activated. Major autophosphorylation sites of VEGFR-2 are located in the kinase insert domain (Tyr951/996) and in the tyrosine kinase catalytic domain (Tyr1054/1059). 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. The phosphorylation of Tyr1212 provides a docking site for Grb2 binding, and phospho-Tyr1175 binds with the p85 subunit of PI-3 kinase and PLCg, as well as Shb. Signaling from VEGFR-2 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.
