It was shown that all 4 peptides were located in neurones, many of which were associated with smooth muscle fibres, suggesting that these peptides are transmitters or modulators at neuromuscular junctions.
Isolation of pyroGlu-Gly-Arg-Phe-NH2 (Antho-RFamide), a neuropeptide from sea anemones.
Three different methods established that the structure of the Anthopleura RFamide peptide (Antho- RFamide) is pyroGlu-Gly-Arg-Phe-NH2, which is proposed that Antho-RFamide is a transmitter at neuromuscular synapses in sea anemones.
Neurons and Their Peptide Transmitters in Coelenterates
Coelenterates have the simplest nervous system in the animal kingdom, and it was probably within this group of animals that nervous systems first evolved. Present day coelenterates are diverse and…
Arg-Phe-amide-like peptides in the primitive nervous systems of coelenterates
Neurones and neuropeptides in coelenterates.
Using immunocytochemistry with antisera to the sequence Arg-Phe-NH2 (RFamide), RFamide-like peptides were demonstrated in the nervous systems of all classes of coelenterates, indicating that these neuropeptides play a role in neurotransmission.
Excitatory Actions of Antho-RFamide, An Anthozoan Neuropeptide, on Muscles and Conducting Systems in the Sea Anemone Calliactis Parasitica
It is concluded that contractions evoked by Antho-RFamide may be partly due to neuronal activity, but probably also involve direct excitation of the muscles.

Neuropeptides in Invertebrates
This chapter is divided into three parts, describing briefly the discovery of some neuropeptides and what can be learned about their occurrence, biosynthesis, action etc.
