Figure 2

Phylogenetic tree of Fugu Non-Rhodopsins. The figure illustrates the members of the Glutamate, Adhesion, Frizzled, Secretin families in Fugu calculated using the neighbor joining (NJ) method based on 1000 replicas of the dataset. The position of the Non-Rhosopsins was established using the 112 receptors of the Fugu non-rhodopsin families. The receptors which lack sequence similarity with any other GPCR family have been categorized as ‘Other 7TM’ and depicted in the phylogenetic tree. The members have been denoted as numerals as per the numbering in Dataset S3.
