"In these cells, three major p85-containing complexes were formed after EGF treatment: ErbB3-p85, Shc-p85, and a multimeric Gab2-Grb2-SHP2-p85, which accounted for more than 80% of total EGF-induced PI3K activity (Kong, M., C. Mounier, J. Wu, and B. I. Posner, J Biol Chem, 2000, 275:36035-36042). More recently, we found that EGF-dependent tyrosine phosphorylation of endogenous Gab2 is essential for EGF-induced DNA synthesis in rat hepatocytes. Here we show that, after EGF treatment, ErbB3-p85 and Shc-p85 complexes were localized to plasma membrane and endosomes, whereas the multimeric Gab2-Grb2-SHP2-p85 complex was formed rapidly (peak at 30 sec) and exclusively in cytosol." . .
