SUMMARY Feeding in starfish is a remarkable process in which the cardiac stomach is everted over prey and then retracted when prey tissue has been resorbed. Previous studies have revealed that SALMFamide-type neuropeptides trigger cardiac stomach relaxation and eversion in the starfish Asterias rubens. We hypothesized, therefore, that a counteracting neuropeptide system controls cardiac stomach contraction and retraction. Members of the NG peptide family cause muscle contraction in other… 
Characterization of NGFFYamide Signaling in Starfish Reveals Roles in Regulation of Feeding Behavior and Locomotory Systems
TLDR
The characterization of the actions of NGFFYamide in starfish indicates that NPS/NG peptide/CCAP-type signaling is an evolutionarily ancient regulator of feeding and locomotion.
Transcriptomic identification of starfish neuropeptide precursors yields new insights into neuropeptide evolution
TLDR
This is the most comprehensive identification of neuropeptide precursor proteins in an echinoderm to date, yielding new insights into the evolution of neuroPEptide signalling systems.
Evolutionarily ancient role of cholecystokinin-type neuropeptide signalling as an inhibitory regulator of feeding-related processes revealed in an echinoderm
TLDR
An evolutionarily ancient role of CCK/SK-type neuropeptides as inhibitory regulators of feeding-related processes in the Bilateria has been conserved in the unusual and unique context of the extra-oral feeding behaviour and pentaradial body plan of an echinoderm.
Discovery of sea urchin NGFFFamide receptor unites a bilaterian neuropeptide family
TLDR
The sea urchin NGFFFamide precursor and receptor are ‘missing links’ in the evolutionary history of neuropeptides that control ecdysis in arthropods (CCAP) and regulate anxiety in humans (NPS).
Pedal peptide/orcokinin‐type neuropeptide signaling in a deuterostome: The anatomy and pharmacology of starfish myorelaxant peptide in Asterias rubens
Pedal peptide (PP) and orcokinin (OK) are related neuropeptides that were discovered in protostomian invertebrates (mollusks, arthropods). However, analysis of genome/transcriptome sequence data has
Biochemical, Anatomical, and Pharmacological Characterization of Calcitonin-Type Neuropeptides in Starfish: Discovery of an Ancient Role as Muscle Relaxants
TLDR
Investigation of the effects of synthetic ArCT on in vitro preparations of the apical muscle and tube feet revealed that it acts as a relaxant, causing dose-dependent reversal of acetylcholine-induced contraction, indicating an evolutionarily ancient role of CT-type neuropeptides that can be traced back to the common ancestor of deuterostomes.
Ancient role of vasopressin/oxytocin-type neuropeptides as regulators of feeding revealed in an echinoderm
TLDR
The discovery that asterotocin triggers fictive feeding in starfish provides important new evidence of an evolutionarily ancient role of VP/OT-type neuropeptides as regulators of feeding in animals.
The evolution of neuropeptide signalling: insights from echinoderms
TLDR
Looking forward, the discovery of multiple neuropeptide signalling systems in echinoderms provides opportunities to investigate how these systems are used to regulate physiological and behavioural processes in the unique context of a decentralized, pentaradial bauplan.
Identification of a novel starfish neuropeptide that acts as a muscle relaxant
TLDR
Data indicate that SMP has a general physiological role as a muscle relaxant in starfish, and the first study to determine the function of a PP/OK‐type peptide in a deuterostome.
Localization of Neuropeptide Gene Expression in Larvae of an Echinoderm, the Starfish Asterias rubens
TLDR
The first multi-gene investigation of larval neuropeptide precursor expression in a species belonging to the phylum Echinodermata—the starfish Asterias rubens is reported, providing novel perspectives on the evolution and development of neuropeptic signaling systems and neuroanatomical insights into neuropePTide function in echinODerm larvae.

NG peptides: a novel family of neurophysin-associated neuropeptides.
SALMFamide neuropeptides cause relaxation and eversion of the cardiac stomach in starfish
TLDR
It is shown that two neuropeptides (S1 and S2) belonging to a family of echinoderm neuropeptic called SALMFamides cause concentration–dependent relaxation of the cardiac stomach in vitro, with S2 being 10 to 20 times more potent than S1.
NGFFFamide and echinotocin: structurally unrelated myoactive neuropeptides derived from neurophysin-containing precursors in sea urchins
TLDR
Both NGFFFamide and echinotocin cause contraction of tube foot and oesophagus preparations from the sea urchin Echinus esculentus, consistent with the myoactivity of NGIWYamide in sea cucumbers and the myOactivity of vasopressin/oxytocin-like peptides in other animal phyla.
The Protein Precursors of Peptides That Affect the Mechanics of Connective Tissue and/or Muscle in the Echinoderm Apostichopus japonicus
TLDR
Interestingly, analysis of the A. japonicus transcriptome reveals that the only protein containing the holokinin sequence PLGYMFR is an alpha-5 type collagen, suggesting that proteolysis of collagen may generate peptides (holokinins) that affect body wall stiffness in sea cucumbers, providing a novel perspective on mechanisms of mutable connective tissue in echinoderms.
Distribution and action of SALMFamide neuropeptides in the starfish Asterias rubens.
TLDR
The production and characterisation of an S2-specific antiserum designated CLII is described, which has been used in a radioimmunoassay to measure S1 and S2 levels in extracts of body parts from the starfish Asterias rubens.

NGIWYamide-induced Contraction of Tube Feet and Distribution of NGIWYamide-like Immunoreactivity in Nerves of the Starfish Asterina pectinifera
TLDR
The results suggest that NGIWYamide or an NGIwYamide-like peptide exists in starfish and functions as a neurotransmitter or a neuromodulator.
Molecular evolution of peptidergic signaling systems in bilaterians
TLDR
This work interrogated genomic sequence databases and used phylogenetic reconstruction tools to show that a large fraction of human PSs were already present in the last common ancestor of flies, mollusks, urchins, and mammals, and indicated that many vertebrate and arthropod PSs that were previously thought to be phyla specific are in fact of bilaterian origin.
The SALMFamides: a new family of neuropeptides isolated from an echinoderm
TLDR
S1 and S2 are the first neuropeptides identified in species belonging to the phylum Echinodermata, and share minimal sequence identity with members of the family of FMRFamide-like peptides so they are designated as founder members of a new family, the SALMFamides.
Localization of the neuropeptide NGIWYamide in the holothurian nervous system and its effects on muscular contraction
TLDR
Labelled nerve fibres from the hyponeural part of the radial nerve running towards the circular muscle and from the podial nerve into the body wall dermis suggest that NGIWYamide controls both muscle and connective tissue.
