title: A molluscan neuropeptide related to the crustacean hormone, RPCH.
abstract: A peptide that potentiates twitch contraction of the radula retractor muscle of the prosobranch mollusc Fusinus ferrugineus was isolated from the ganglia of the animal. Its primary structure is H-Ala-Pro-Gly-Trp-NH2 (APGWamide) closely related to the C-terminal tetrapeptide of the crustacean red-pigment-concentrating hormone. APGWamide showed modulatory actions on contractions in various molluscan muscles.
