Evolution of RPLP1 CNE over at least 670 million years. a Alignment of RPLP1 CNE in all organisms where detected. Sequence logo diagrams of each conserved motif are shown below the alignment. Motif 1a is protostome-specific whereas motif 1b appears to be the ancestral and deuterostome form. Motifs 2 and 3 are variably spaced and are present in all phyla examined. Species name color scheme matches that of Fig. 5. b Diagram showing the position and spacing of each motif in each organism in relation to the translation start site. Genus/species abbreviations are defined in Additional file 2: Table S10
