Predicted evolutionary relationships of PABPs. Full-length PABP sequences were compiled from various databases (see Additional data files) and aligned using the CLUSTALW program at the European Bioinformatics Institute [122]. The tree was constructed using the neighbor-joining method [123] and drawn using Phylodendron [124]. The scale bar represents 0.1 substitutions. In the instances where no PABP name is given, only a single PABP protein has been identified in that organism.
