Abstract
We report the isolation and molecular characterization of the mouse grb2 gene. The product of this gene, the Grb2 protein, is highly related to the Caenorhabditis elegans sem-5 gene product and the human GRB2 protein and displays the same SH3-SH2-SH3 structural motifs. In situ hybridization studies revealed that the mouse grb2 gene is widely expressed throughout embryonic development (E9.5 to P0). However, grb2 transcripts are not uniformly distributed, and in certain tissues (e.g., thymus) they appear to be regulated during development. Recent genetic and biochemical evidence has implicated the Grb2 protein in the signaling pathways that link cell surface tyrosine kinase receptors with Ras. We have investigated the association of the Grb2 protein with epidermal growth factor (EGF) and nerve growth factor (NGF) receptors in PC12 pheochromocytoma cells. EGF treatment of PC12 cells results in the rapid association of Grb2 with the activated EGF receptors, an interaction mediated by the Grb2 SH2 domain. However, Grb2 does not bind to NGF-activated Trk receptors. Mitogenic signaling of NGF in NIH 3T3 cells ectopically expressing Trk receptors also takes place without detectable association between Grb2 and Trk. These results suggest that whereas EGF and NGF can activate the Ras signaling pathway in PC12 cells, only the EGF receptor is likely to do so through a direct interaction with Grb2. Finally, binding studies with glutathione S-transferase fusion proteins indicate that Grb2 binds two distinct subsets of proteins which are individually recognized by its SH2 and SH3 domains. These observations add further support to the concept that Grb2 is a modular adaptor protein.
