Disruption of p120 Ras-GAP/p190 interaction in S7A cellular lysates by inhibitory p190 synthetic peptides. Lanes 1–4, no peptide; lanes 5 and 6, diphosphotyrosine peptide; lanes 7 and 9, Peptide 1 phosphonopeptide; lanes 8 and 10, Peptide 2 phosphonopeptide. 50 μM peptide, 200 μg of total S7A cellular lysate, and 10 μg of GST-Ras-GAP fusion proteins were used for all mixing experiments. Samples were subject to blotting with anti-p190 antibodies.
