Identification of sites on epidermal growth factor receptors which are phosphorylated by pp60src in vitro.

Abstract excerpt

The Epidermal Growth Factor Receptor (EGF-R) becomes constitutively tyrosine phosphorylated on two novel sites in v-Src transformed cells, and these phosphorylations are associated with enhanced signaling activity [1]. To determine whether Src could directly phosphorylate these sites, we have examined the ability of the Src kinase to phosphorylate both wild-type and kinase-defective EGF-Rs in vitro. Although...
