A neuropeptide of the blowfly Calliphora vomitoria with an amino acid composition homologous with vertebrae pancreatic polypeptide.

A neuropeptide purified from the brain of the blowfly (Calliphora vomitoria) that cross-reacts in a bovine pancreatic polypeptide radioimmunoassay has been subjected to amino acid analysis. The amino acid composition of the peptide shows homology with vertebrate pancreatic polypeptide species. Amounts of the neuropeptide calculated from amino acid analysis… (More)
