A peptide that relaxes catch tension of the anterior byssus retractor muscle of Mytilus edulis was purified from pedal ganglion extracts of the mussel. Its primary structure was determined to be H-Ala-Met-Pro-Met-Leu-Arg-Leu-NH2. This peptide was found to have not only catch-relaxing action on the byssus retractor muscle but also modulatory actions on contractions in various molluscan muscles.

UI MeSH Term Description Entries
D009119 Muscle Contraction A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.
