The epidermal growth factor receptor is covalently linked to ubiquitin.


Incubation of cultured human fibroblasts with epidermal growth factor (EGF) causes a proliferative response that is mediated by the binding of the growth factor to specific cell surface receptors. One event that occurs rapidly following EGF binding is the covalent modification of the EGF receptor (EGF-R) by phosphorylation on Ser, Thr, and Tyr residues… (More)
