Figure 5. Amino Acid conservation of the P387 and R552 residues in other PDE6β orthologs. The arrows point to the amino acid residues P387 and R552, which are mutated in the affected individuals of families PKRP183 and PKRP161, respectively. Primates are colored green, placental mammals are blue, and vertebrates are purple.
