Figure 1

Phylogenetic relationship and molecular sequence of OT/VP-like neuropeptides. Taxonomic groups and neuropeptide names (in brackets). Conserved cysteines are highlighted in yellow, and the disulfide bond between Cys1 and Cys6 is indicated. *C-terminus amidated; #Renamed to arachnotocin to simplify nomenclature. Analogous to the existing phylum nomenclature, we refer to the mite-derived peptide by I8-arachnotocin, to distinguish it from arachnotocin (also referred to as crustacean OT/VP-like peptide in the past)20,21.
