Maximum likelihood tree showing phylogenetic relationships of the coronin 7 and other paralogous families. (A) Coronin families and classes are indicated as previously defined . Nodal support was obtained using MEGA 5.2 with 500 bootstrap replicates and posterior probability (PP) was estimated using MrBayes version 3.1.2. Support values are shown for all major nodes defining the clusters. Nodes with PP > 0.9 are shown as black circles and the corresponding percentage bootstrap values are shown. (B) Predicted domain architectures using Pfam search (default settings) are shown for the coronin 7 family.
