Figure 1.

AphC.like proteins in sponges.A. The coding regions are indicated by green rectangles, the untranslated regions by blue rectangles, and the SECIS elements by orange rectangles. An intron is indicated by lines connecting the exons. The position of each site in the sequence of the chromosome or scaffold is shown by numbers and bottom coordinates. The position of the Sec-TGA codon is highlighted by the rectangular box around the number. B. The multiple alignment of AphC.like proteins and 4 Sec-containing prokaryotic AphC proteins are shown with Sec residues highlighted with a green background. Species names are listed on the left. C. The SECIS elements of all Aq.AphC.like genes of Amphimedon queenslandica are shown with Cove Scores.
