From: Phylogenetic analysis of 277 human G-protein-coupled receptors as a tool for the prediction of orphan receptor ligands

Figure 3

Chemokine receptors (subgroups A1 and A2). Phylogenetic trees of the subgroups were inferred using Puzzle 5.0 corrected by the JTT substitution frequency matrix. Quartet-puzzling support percentage values from 10,000 puzzling steps are shown. The scale bars indicate a maximum likelihood branch length of 0.1 inferred substitutions per site. Orphan receptors are shaded.
