Vascular endothelial growth factor receptor 2 (VEGFR-2, KDR, Flk-1) is a major receptor transducing the effects of VEGF into endothelial cells. Upon binding to specific ligands, 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 the adaptor proteins, including Shc, Grb-2, PI3 kinase, Nck and the protein tyrosine phosphatases SHP-1 and SHP-2. The signaling of VEGFR-2 is necessary for the execution of VEGF-stimulated proliferation, chemotaxis and prouting, as well as survival of cultured endothelial cells in vitro and angiogenesis in vivo.
