Phylogeny of invertebrate specific D1-like receptor (InvD1L) and its sister clade, alpha-1 adrenergic receptor (ADRA1). (A) Comprehensive phylogenetic analysis of DA receptors and ADRA1 sequences. The sequences belonging to the D2 cluster of DA receptors (dotted line, yellow background) were not included in this analysis and were added manually to this phylogenetic tree. The tree was constructed using an unweighted pair-group method with arithmetic mean (UPGMA) test. Numbers at the nodes are for the percent supports in 500 bootstrap replicates. (B) Hypothetical evolutionary scenario for InvD1L (magenta) and ADRA1 (green) receptors. Note that divergence of the two receptors likely occurred in the early Bilateralia, while InvD1L was lost in the early Chordata and ADRA1 was lost in Insecta. (C) Table summarizing the synonyms commonly used for different DA receptors of I. scapularis and D. melanogaster.
