Post-transcriptional regulation of ribosome biogenesis. A) Genes from the clusters for ribosome biogenesis and related protein assembly and cellular component organization containing statistically significant and conserved RNA motifs in their 3' UTR first 300 bases. The two motifs (see logos) have positional and directional bias and sometimes appear as a combined motif. The genes are listed in the displayed ordering in Table 3. The predicted structure of the motif with the highest likelihood score is also shown. B) Post-transcriptional cis-regulation at these motifs is tested against previously published experimental data [21]. The red points mark the transcriptomic versus proteomic levels of the genes with the motifs while the blue points depict that for genes from the same clusters without the motifs.
