WebJan 25, 2024 · Grb2 and SOS doublets in two-color single-molecule imaging were isolated with the criteria that the distance between a paired Grb2 and SOS is less than 30 nm. For simplicity, a Grb2 or SOS molecule with multiple neighboring molecules that is within 30 nm were excluded in this analysis. All detected Grb2 and SOS doublets were isolated pairs. WebGRB2 serves as an adapter molecule that contains both SH2 and SH3 domains. GRB2 binds to phosphotyrosine residues on activated receptor tyrosine kinases via its SH2 domain and binds to the guanine nucleotide exchange factor Sos via two SH3 domains. Sos then binds to and activates the Ras protein. Although
