Rib binding of RPGs across the Drosophila genome and the position of the corresponding proteins on the ribosomal subunit structures. (Related to Fig. 4.) (A)Drosophila RPG loci are dispersed across all chromosomes. Colored flags represent RPGs bound by Rib (log₁₀ binding likelihood threshold ≥4). Unfilled flags represent genes not bound by Rib (log₁₀ binding likelihood threshold <4). Relative gene positions are approximate representations based on the standard cytogenetic map (FlyBase, FB2017_04). Yellow, genes bound by Rib in both fkh-GAL4 and sage-GAL4 driver tracks; red, genes bound by Rib in the fkh-GAL4 track only; green, genes bound by Rib in the sage-GAL4 track only. (B) Rib binds to genes encoding for proteins of both the 40S and the 60S ribosomal subunits. The proteins for which the corresponding genes lack Rib binding in the ChIP-seq are shown in gray for the 40S subunit and in purple for the 60S subunit.
