Phylogeny of C family GPCRs from zebrafish, fugu, goldfish and mouse. A phylogenetic tree of selected zebrafish, fugu, goldfish and mouse C family receptors was constructed using a maximum likelihood algorithm and displayed in radial format. Groups I – V all form clades distinct from the CaSR, T1R, mGluR and GABA-B families. Most of the fish OlfC receptors form a clade (Group I) distinct from the mouse V2R receptors (mmV2R) found in Groups II, IV and V. Group II contains both fish OlfC receptors (zebrafish: drOlfCc1; goldfish: ca5.3; fugu: 735220) and mouse V2R2-like (mmV2R2) sequences. Group III contains receptors from zebrafish (drOlfCa1), goldfish (ca5.24), fugu (179742) and mouse (mmGprc6a). Scale bar indicates the number of amino acid substitution per site.
