Role of Y1212 VEGFR2 signaling transduction

The project concerns vascular endothelial growth factor (VEGF) signaling, which is dependent on binding of VEGF to VEGF receptor-2 (VEGFR2) and leads to activation of the receptor kinase and autophosphorylation. Previous mouse studies with the VEGFR-2 phosphorylation site mutation Y1212F showed reduced vascular stability. We here investigate with LC-MS proteomics which signal transduction pathway(s) are lost in the mutant by identifying proteins that bind to the Y1212F site.
