Abstract excerpt
The epidermal growth factor (EGF) receptor contains multiple sites of phosphorylation on serine, threonine, and tyrosine residues. Because the biological responsiveness of the EGF receptor is regulated by phosphorylation at several of these sites, we studied the functional consequences of removal of the Thr669 and Ser671 phosphorylation sites using site-directed mutagenesis. The mutant EGF receptor expressed in...
