From: Discovery of peptide probes to modulate oxytocin-type receptors of insects

Comparison of insect inotocin and human oxytocin/vasopressin receptor sequences in transmembrane helical domains. Amino acid sequence alignments, performed with Clustal Omega, of the transmembrane helices of each receptor are shown vertically, with homologous regions highlighted in Boxshade representation. Receptor sequences are, from left to right, T. castaneum inotocin receptor, L. niger inotocin receptor (separated with a red line), human oxytocin receptor, human vasopressin V1a receptor, human vasopressin V2 receptor and human vasopressin V1b receptor.
