Suppose that, through genetic manipulations, a chimeric receptor is produced that consists of the extracellular domain of the insulin receptor and the transmembrane and intracellular domains of the EGF receptor. Cells expressing this receptor are exposed to insulin, and the level of phosphorylation of the chimeric receptor is examined. What would you expect to observe and why? What would you expect to observe if these cells were exposed to EGF?
