Binding of the Grb2 SH2 domain to phosphotyrosine motifs does not change the affinity of its SH3 domains for Sos proline-rich motifs.
Phosphotyrosine peptide binding to Grb2 induces tryptophan fluorescence changes in the Src homology 2 (SH2) domain. Affinities are in the nanomolar range, the Shc peptide having the highest affinity, followed by peptides mimicking Grb2 binding sites on EGF and HGF receptors, the putative sites on in...
