PC12 cell activation by epidermal growth factor receptor: role of autophosphorylation sites

PC12 cells have been used as a model system for neuronal differentiation due to their ability to alter their phenotype to a sympathetic neuron-like cell in response to nerve growth factor or fibroblast growth factor. Under some conditions, epidermal growth factor (EGF) can also induce PC12 cells to differentiate. To study signaling from the EGF receptor without the confounding effects of endogenous EGF receptors we generated a chimeric receptor...
