Figure 2. Motifs or consensus sequences of regulated phosphorylation events identified in Ras-transformed HBECs and NSCLC cells.

(A) The numbers of comparable phosphopeptides subjected to quantitative proteomics analysis and the upregulated and downregulated phosphopeptides identified in each pair of cell lines are shown. (B) Representative motif sequences were extracted from the regulated phosphopeptides using motif-x. The motifs with significance of p<10⁻¹⁰ are shown.
