Kinase-active SRC phosphorylates EGFR on Y869. 5 / 5
5 |

"When co-overexpressed, the epidermal growth factor receptor (EGFR) and c-Src cooperate to cause synergistic increases in EGF-induced DNA synthesis, soft agar colony growth, and tumor formation in nude mice. This synergy is dependent upon c-Src-mediated phosphorylation of a unique tyrosine on the EGFR, namely, tyrosine 845 (Y845). "

"TGF-beta1-stimulated PAI-1 expression, moreover, was preceded by EGFR phosphorylation on Y845 (a src kinase target residue) and required pp60(c-src) activity."

"Since Tyr-845 of EGFR is a known Src target, we next determined whether hyperphosphorylation of this site under cigarette smoke was due to Src kinase activation."

"As Tyr-845 is a c-Src target.; phosphorylation of Tyr-845 in the EGFR"

"In this study, we demonstrated that c-Src-dependent phosphorylation of tyrosine 845 (Tyr 845) on EGFR was required for DNA synthesis induced by the G protein-coupled agonists, endothelin (ET) and lysophosphatidic acid (LPA), and the cytokine, growth hormone (GH), in murine fibroblast and breast cancer model systems.
