Figure 4

Multi-species nucleotide PIP for the PDE4B gene. PDE4B gene sequences from multiple species were aligned to human PDE4B using MultiPIP maker. Both duplicates are shown for the Trub PDE4B gene isoform. PIP output files were cropped to display only the exons of interest. The 5' exons for the PDE4B long forms PDE4B1 and PDE4B3 are colored blue, the short form PDE4B2 is colored cyan, and the super-short form PDE4B5 is colored orange. Vertical dotted lines represent breaks in the nucleotide sequence, and nucleotide positions as referenced to Hsap PDE4B along the bottom scale. The range of nucleotide percent identities shown (between 50% and 100%) is indicated in the upper right corner of the plot.
