Kinase activity of EGFR is responsible for lateral phosphorylation. + and − indicate the presence and absence of EGF ligand. Lanes from left to right, WT EGFR (−), WT (+), R776H (−), R776H (+), D855G (−), D855G (+), R776H/D855G (−), R776H/D855G (+), D855G and L704N/V948R (−), D855G and L704N/V948R (+), R776H/D855G and L704N/V948R (−), R776H/D855G and L704N/V948R (+), Y1197F and R776H/V948R (−), Y1197F and L704N/V948R (+), R776H/Y1197F and R776H/V948R (−), R766H/Y1197F and L704N/V948R (+) L704N/V948R is FLAG tagged. All other constructs are GFP tagged.
