	The rational nomenclature of kaliseptine is kappa-actitoxin-Avd6a. The first letter Kappa indicates its molecular target, namely a voltage-gated potassium channel. Actitoxin is a neurotoxin derived from the Actiniidae. Avd denotes that it is extracted from "Anemonia viridis". Finally, 6a specifies that this was the sixth Acititoxin of which the full-length amino acid sequence was published and that this is the first isoform.
