Figure 5.
eS25/RPS25 is heterogeneous between fetal and adult ribosomes in mice, with a potential consequence on selective mRNA translation. (A) Enrichment score 1 (RPSEA) heatmap for different RPs (rows) in dripARF ribosome heterogeneity predictions in selected comparisons (columns). Predictions are based on Ribo-seq data (20), generated with the adult and fetal stage of 6 organs in mice; heart, retina, liver, kidney, lung and brain. (B) Closer look at rRNA fragment abundance change at rRNA positions in the eS25/RPS25 vicinity shows consistency across fetal-vs-adult comparisons. In this figure, the layout is the same as Figure 2C. (C) Translation efficiency changes in adult-vs-fetal comparisons, and mRNA association with eS25-enriched ribosomes is significantly associated with mRNA CDS length. In the figure, CDS length (y-axis) distribution of genes are given separately for each comparison, where genes are separated on the x-axis, into different TE groups for the first dataset and into association groups with specific ribosome populations for the second dataset.
