Figure 2From: Functional characterization of two melanocortin (MC) receptors in lamprey showing orthology to the MC1 and MC4 receptor subtypesPhylogenetic analysis of full-length amino acid sequences of MC receptors from human, chicken, zebrafish and lamprey. The consensus tree was generated by Neighbor-Joining analysis (Phylip 3.6a3). The numbers above the nodes indicate bootstrap replicates. The abbreviations used: Hsa, human; Gga, chicken; Dre, zebrafish and Lfl, lamprey. The accession numbers are listed in "Methods".Back to article page
