Figure Lengend Snippet: Upstream kinase/regulator analyses based on the regulated phosphoproteome data. A, Heatmap of the over-representation p values calculated for each predicted kinase using PhosphoSiteAnalyzer. The subset “serum (−)” indicates SILAC ratio > 2.0, whereas “serum (+)” shows SILAC ratio < 0.5. TGFBR2 and ACVR2A/B-specific phosphorylation sites were predicted to be significantly enriched in the “serum (−)” subset (adjusted p value < 0.05). B, Upstream regulator analysis by IPA. The top ten upstream regulators relevant to the regulated phosphoproteome are shown with the corresponding score (−log [p value]). C, IPA-based description of TGF-β1 and the target molecules in our phosphoproteome data. Red indicates increased phosphorylation in serum-free cultured GB2 cells, whereas green shows increased phosphorylation in serum cultured cells. Dashed lines represent indirect interactions caused by TGF-β1.
