Volcano plots display difference in phosphorylated peptide abundance between cells retrieved at 1, 5, 15, and 30 min post-UV-C (500 J/m2) and untreated (UT) sample (seeFigure S1F). ZAK, GCN2, p38, and JNK (and their known effectors) are colored according to (A). Statistically up- or down-regulated phosphopeptides determined by two-sided Welch’s t test (adjusted to 1% FDR for multiple comparisons). Dotted lines delineate 1.5-fold change (x axis) and 0.05pvalue (y axis). SeeFigures S1S4,Table S1, andData S1.
