Schematic overview of the RPSA (pseudo)genes. The genomic structure of the ovine RPSA gene is drawn in part A, the mRNA of the RPSA gene is drawn in part B. Part C represents the genomic structure of the different RPSA pseudogenes. The squares represent exons and the lines stand for introns. The coding sequence (CDS) is drawn in yellow; the untranslated sequences in green. The blue squares are parts of the pseudogene sequence that are analogous with the exons of the RPSA mRNA. The pink squares symbolize interspersed sequences and the white gaps deletions. SNORA62 is represented as a black square. Start codons and stop codons, analogous with the ones of RPSA, are represented by a dotted line.
