"Upon EGFstimulation of the cell, binding of Sos to the EGF receptor-Grb2 complex brings a significant portion of Sos to the membrane (Figure 5)."

"We only considered this effect for the assembly of the EGFR, Grb2, and Sos complex, but other components of the EGRF signaling network may also decrease their mobility upon activation."

"As expected, mutation of the Grb2 binding site significantly reduced the interaction of Grb2 and SOS with EGFR ( xref )."

"Following EGFR activation, Grb2 and Sos (adaptor proteins) bind EGFR directly at Y1092 and Y1110 or through Shc (which binds at EGFR Y1172 and Y1197) [ xref ]."

"In contrast to the activated epidermal growth factor receptor that binds the GRB2-Sos complex directly, activation of the insulin receptor results in the interaction of GRB2-Sos with IRS-1 and Shc, thus linking the insulin receptor to Ras signaling pathways."

"The binding of the Grb2 adaptor protein and the associated SOS protein (a Ras Guanine nucleotide Exchange Factor) to the EGFR results in the activation of the membrane associated Ras GTPase, and subsequently activation of the MAPK cascade consisting of Raf, MAPK/ERK Kinase (MEK) and Extracellular Regulated Kinase (ERK) xref ."

"Using epidermal growth factor (EGF) receptor, Grb2 and Sos proteins as an example, we demonstrated the use of the three-hybrid system to detect formation of a three-component complex, i.e., the Grb2-mediated interactions between EGF receptor and Sos."
