Boxplots with outlier calling showing the significant codon biases in Dnmt2 down-regulated and up-regulated proteins in the DML and dSILAC datasets. For the dSILAC (S-All) dataset, we display the plot for all identified proteins or stromal (S-St) and suspension (S-Ss) cells. A significant increase or decrease of a codon frequency in up- or down-regulated proteins relative to the average frequency of that codon in all identified proteins is displayed as a colored dot. Codons showing no deviation from average values are grouped together in the box.
