Figure 1From: Cross genome phylogenetic analysis of human and Drosophila G protein-coupled receptors: application to functional annotation of orphan receptorsPhylogenetic trees of peptide receptors (clusters 1–11). Trees were inferred as described in Methods (using TREE-PUZZLE 5.1 corrected using JTT substitution frequency matrix. Quartet-puzzling support percentage values from 10,000 puzzling steps are shown). Out-group not showed in the figure. The scale bars indicate a maximum likelihood branch length of 0.1 inferred substitutions per site. Orphan receptors are shown in bold letters. Cluster numbers are marked in the top left corner.Back to article page
