The C-terminal SH3 domain of the adapter protein Grb2 binds with high affinity to sequences in Gab1 and SLP-76 which lack the SH3-typical P-x-x-P core motif


The adapter Grb2 is an important mediator of normal cell proliferation and oncogenic signal transduction events. It consists of a central SH2 domain flanked by two SH3 domains. While the binding specificities of the Grb2 SH2 and N-terminal SH3 domain [Grb2 SH3(N)] have been studied in detail, binding properties of the Grb2 SH3(C) domain remained poorly… (More)
