A group of neuropeptide hormones including substance P, substance K (neurokinin A) and neurokinin B in mammals, eledoisin from Octopus and physalaemin (amphibian). All have 10 or 11 residues with a common -FXGLM-NH2 ending. Elicit a wide range of responses from neurons, smooth muscle, endothelium, exocrine glands and cells of the immune system; effects similar in many ways to bradykinin and serotonin.
A family of biologically active peptides sharing a common conserved c-terminal sequence, -phe-x-gly-leu-met-nh2, where x is either an aromatic or a branched aliphatic amino acid. Members of this family have been found in mammals, amphibians, and mollusks.
