Figure EV2. Codon optimality in mosquito and across species.
(A) Pair plot showing the CSC calculated in mosquito C6/36 cells using indicated transcription inhibitors. Lower triangle shows scatterplots of CSCs between inhibitors. Diagonal shows density plot of CSC for each inhibitor. Upper triangle shows Pearson correlation coefficient of CSCs between inhibitors. (B) Heatmap showing Spearman rank correlations between known CSCs in indicated species. P = 8.91e–05 for Human/Mosquito, P = 1.08e–05 for Human/Zebrafish, P = 4.13e–01 for Human/Frog, P = 0.343 for Human/Yeast, P = 7.94e–03 for Human/Fly, P = 3.25e–05 for Mosquito/Zebrafish, P = 9.29e–03 for Mosquito/Frog, P = 0.000181 for Mosquito/Yeast, P = 4.13e–14 for Mosquito/Fly, P = 8.70e–09 for Zebrafish/Frog, P = 0.0295 for Zebrafish/Yeast, P = 4.87e–06 for Zebrafish/Fly, P = 0.00562 for Frog/Yeast, P = 9.31e–06 for Frog/Fly, P = 1.97e–07 for Yeast/Fly. Color of the tile indicates correlation coefficient. *P < 0.05, **P < 0.01, ***P < 0.001. (C) 1nt frameshift reporters designed based on mosquito codon optimality were co-transfected into 293T human cells with a vector encoding for mCherry as an internal control. Bar plots showing that the 1nt frameshift reporter enriched in optimal codons displayed higher GFP/mCherry fluorescence intensity than its nonoptimal counterpart measured by flow cytometry analysis. Results are shown as the averages of GFP/mCherry fluorescence intensity ± standard error of the mean from two independent experiments with four biological replicates per experiment (P = 2.524e–8, unpaired t test).
