GRB2 is a small adaptor protein of 217 amino acids comprising one SH2 domain surrounded by two SH3 domains. GRB2 couples receptor tyrosine kinase activation to Ras signalling by interacting, through its SH3 domains, to the carboxy-terminal proline-rich regions of the guanine nucleotide exchange factor Sos. Here we report the synthesis and solution structure of the amino-terminal SH3 domain of GRB2 and of its more stable Ser 32 mutant. 1H NMR analysis of the complex between the Ser-32-GRB2-N-SH3 domain and the proline-rich peptide VPPPVPPRRR, derived from h-Sos, shows that relative to the SH3 peptide complexes described for PI3K, Fyn and Abl, the proline-rich peptide in this complex binds in the opposite orientation.
