@article { , title = {Complex formation between VEGFR2 and the β2-adrenoceptor}, abstract = {Vascular endothelial growth factor (VEGF) is an important mediator of endothelial cell proliferation and angiogenesis via its receptor VEGFR2. A common tumor associated with elevated VEGFR2 signaling is infantile hemangioma that is caused by a rapid proliferation of vascular endothelial cells. The current first-line treatment for infantile hemangioma is the β-adrenoceptor antagonist, propranolol, although its mechanism of action is not understood. Here we have used bioluminescence resonance energy transfer and VEGFR2 genetically tagged with NanoLuc luciferase to demonstrate that oligomeric complexes involving VEGFR2 and the β2-adrenoceptor can be generated in both cell membranes and intracellular endosomes. These complexes are induced by agonist treatment and retain their ability to couple to intracellular signaling proteins. Furthermore, coupling of β2-adrenoceptor to β-arrestin2 is prolonged by VEGFR2 activation. These data suggest that protein-protein interactions between VEGFR2, the β2-adrenoceptor, and β-arrestin2 may provide insight into their roles in health and disease.}, doi = {10.1016/j.chembiol.2019.02.014}, eissn = {2451-9448}, issue = {6}, journal = {Cell Chemical Biology}, pages = {830-841.e9}, publicationstatus = {Published}, publisher = {Elsevier}, url = {https://nottingham-repository.worktribe.com/output/1602383}, volume = {26}, keyword = {VEGFR2, β2-adrenoceptors, Ligand binding, BRET, NanoBRET, Receptor oligomerization, β-arrestin, CRISPR/Cas9}, year = {2019}, author = {Kilpatrick, Laura E. and Alcobia, Diana C. and White, Carl W. and Peach, Chloe J. and Glenn, Jackie R. and Zimmerman, Kris and Kondrashov, Alexander and Pfleger, Kevin D.G. and Friedman Ohana, Rachel and Robers, Matthew B. and Wood, Keith V. and Sloan, Erica K. and Woolard, Jeanette and Hill, Stephen J.} }
