WebIntracellular signaling pathways for VEGFA (vascular endothelial growth factor A)/VEGFR2 (VEGF receptor 2). On ligand binding, VEGFR2 dimerizes and activates its receptor tyrosine kinase activity, which results in autophosphorylation of the intracellular domains. This can then lead to activation of a variety of signaling pathways. WebAngiogenesis, or formation of new blood capillaries from preexisting vessels, plays both beneficial and damaging roles in the organism.
