Molecular cloning of the mouse grb2 gene: differential interaction of the Grb2 adaptor protein with epidermal growth factor and nerve growth factor receptors.

abstract：:Epidermal growth factor (EGF) receptor (EGFR) has been implicated in tumor development and invasion. Dimerization and autophosphorylation of EGFR are the critical events for EGFR activation. However, the regulation of EGF-dependent and EGF-independent dimerization and phosphorylation of EGFR has not been fully underst...
