The HGF-mediated association of Gab1 with either full-length GST-p85 or its isolated N- or C-terminal SH2 domains was inhibited by approximately 50% in the setting of ERK inhibition, a result confirmed by co-immunoprecipitation of the native proteins. A 14-amino acid peptide encoding (472)YVPMTP(477) (one of the major p85 binding sites in Gab1 and the predicted ERK phosphorylation site) was synthesized with either phosphotyrosine alone (pY), or phosphotyrosine + phosphothreonine (pYT). In both pull-down assays and competition assays, pYT demonstrated a higher affinity for p85 than did pY alone. Finally, examination of the phosphorylation state of Akt after HGF stimulation revealed that ERK inhibition resulted in a decrease in Akt activation at both 5 and 10 min. These results suggest that activated ERK can phosphorylate Gab1 in response to HGF stimulation and thereby potentiate the Gab1/PI3K association and subsequent PI3K activation."xsd:string |
