The interaction between epidermal growth factor (EGF) and its target cells has been used as a model for studying the regulation of cell proliferation. Many of the details of binding and subsequent internalization and degradation of this growth factor have been elucidated by following the fate of [125I]EGF in the presence of responsive cells. To investigate the membrane-localized biochemical consequences of EGF-receptor complex formation, a subcellular membrane system has been developed. In this system, EGF enhances phosphorylation of its receptor as well as other endogenous proteins. This EGF-stimulable protein kinase activity is not separated from the EGF receptor activity either by detergent solubilization or by affinity purification of the solubilized membranes. The data suggest that the EGF-binding activity and EGF-sensitive protein kinase activity reside in a single membrane protein. |
