Purification notes
The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated VEGFR 2. The final product is generated by affinity chromatography using a VEGFR 2 derived peptide that is phosphorylated at Tyrosines 1054 and 1059. -

Function
Receptor for VEGF or VEGFC. Has a tyrosine-protein kinase activity. The VEGF-kinase ligand/receptor signaling system plays a key role in vascular development and regulation of vascular permeability. In case of HIV-1 infection, the interaction with extracellular viral Tat protein seems to enhance angiogenesis in Kaposi's sarcoma lesions. -
Involvement in disease
Defects in KDR are associated with susceptibility to hemangioma capillary infantile (HCI) [MIM:602089]. HCI are benign, highly proliferative lesions involving aberrant localized growth of capillary endothelium. They are the most common tumor of infancy, occurring in up to 10% of all births. Hemangiomas tend to appear shortly after birth and show rapid neonatal growth for up to 12 months characterized by endothelial hypercellularity and increased numbers of mast cells. This phase is followed by slow involution at a rate of about 10% per year and replacement by fibrofatty stroma. -
Sequence similarities
Belongs to the protein kinase superfamily. Tyr protein kinase family. CSF-1/PDGF receptor subfamily.
Contains 7 Ig-like C2-type (immunoglobulin-like) domains.
Contains 1 protein kinase domain. -
Post-translational
modificationsPhosphorylated. Dephosphorylated by PTPRB. Dephosphorylated by PTPRJ at Tyr-951, Tyr-996, Tyr-1054, Tyr-1059, Tyr-1175 and Tyr-1214. -

Immunocytochemistry/ Immunofluorescence - Anti-VEGF Receptor 2 (phospho Y1054 + Y1059) antibody (ab5473)ab5473 staining VEGF Receptor 2 (phospho Y1054 + Y1059) in 90% confluent log phase Human umbilical vein endothelial cells (panel a) by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 1% BSA for 1 hour at room temperature. Samples were incubated with primary antibody (2 ug/ml in 0.1% BSA) for 3 hours at room temperature. An Alexa Fluor® 488-conjugated Goat anti-rabbit IgG polyclonal was used as the secondary antibody (1/2000). Nuclei stained blue with DAPI (panel b), F-actin stained red with Alexa Fluor® 555 Rhodamine Phalloidin (panel c), merged image shown in panel d.

Western blot - Anti-VEGF Receptor 2 (phospho Y1054 + Y1059) antibody (ab5473)Peptide Competition and Stimulation: Extracts prepared from PAE cells transfected with a chimeric receptor (see Positive Controls section above for full description) were left unstimulated (1, 2) or stimulated with VEGF (3-8), then were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4°C, then were incubated with a VEGFR2 pan antibody (1, 3) or 0.50µ g/mL VEGFR2 ab5473 antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with: no peptide (2, 4, 5), the non-phosphopeptide corresponding to the immunogen (6), a generic phosphotyrosine containing peptide (7), or, the phosphopeptide immunogen (8). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and bands were detected using the Tropix WesternStar method. The data show that only the peptide corresponding to ab5473 blocks the antibody signal,
