From: Rab32 and Rab38 genes in chordate pigmentation: an evolutionary perspective

Fig. 1

Evolution of the Rab32 and Rab38 subfamily in deuterostomes. Numbers at the branches indicate replicates obtained using the Maximum Likelihood estimation method. 247 sites were used for tree inference. Colored boxes highlight three classes of proteins: Rab7L1 present in invertebrates and vertebrates (blue box), Rab32LO present in protostomes, echinoderms and cephalochordates (yellow box), the Rab32 and Rab38 cluster present in all the deuterostomes (red box). Black arrow indicates the acquisition of FALK amino acid stretch at the stem of Rab7L1, Rab32LO, Rab32 and Rab38 evolution. Triangles indicate monophyletic clades belonging to Rab supergroup III (Rab7, Rab9, Rab23)
