From: The repertoire of G-protein-coupled receptors in Xenopus tropicalis
Phylogenetic tree of the non-rhodopsin receptors. The tree was calculated using the neighbour-joining method with 1000 bootstrap replicas. The 339 CaSR like receptors in Glutamate receptors were represented by 25 members in this group using CD-HIT 40% sequence identity. The position of the Rhodopsin family was established by including twelve random receptors from the Rhodopsin family.
