摘要: Src-homology 3 (SH3) domains mediate signal transduction by binding to proline-rich motifs in target proteins. We have determined the high-resolution NMR structure of complex between amino-terminal SH3 domain GRB2 and a ten amino acid peptide derived from guanine nucleotide releasing factor Sos. The data show that adopts conformation left-handed polyproline type II helix interacts with three major sites on domain. orientation bound is opposite peptides AbI, Fyn p85.
