While we do not discount the possibility that the first two explanations may be valid for some of the confusion in the literature, in this report we show evidence that Src can phosphorylate the EGF-R on novel sites in vitro, that Src and P85α preferentially associate with the EGF-R after it has been phosphorylated by Src, that these Src-phosphorylated sites (including consensus binding sites for Src and P85α) are phosphorylated in cells in response to EGF, that P85α and Src bind to the EGF-R in these cells in an EGF-dependent manner, and that Csk-inactivated Src is reactivated upon binding to the Src phosphorylated EGF-R.
