Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Phospho-VEGF Receptor 2 (Tyr951) Antibody detects transfected VEGFR-2 only when phosphorylated at Tyr951.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic phospho-peptide (KLH-coupled) corresponding to residues surrounding Tyr951 of human VEGFR-2. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts of CKR/PAE cells expressing chimeric receptors containing human CSF-1 extracellular binding domain/mouse VEGFR-2 intracellular domains (Rahimi, N. et al. [2000] J. Biol. Chem. 275, 16986-16992), using Phospho-VEGF Receptor 2 (Tyr951) Antibody (upper) or VEGF receptor 2 antibody (lower).
Background
Vascular endothelial growth factor receptor 2 (VEGFR2, KDR, Flk-1) is a major receptor transducing 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).
