Abstract
The isolation and primary structure of a novel gastrointestinal peptide, designated valosin, is described. The peptide was purified from porcine upper gut extracts using an HPLC and N-terminal sequence screening strategy which depends on Chromatographic and structural characteristics as isolation criterion. The amino acid sequence of this peptide consists of 25 amino acid residues: V Q Y P V E H P D K F L K F G M T P S K G V L F Y. It does not show structural homology to known protein or nucleotide sequences. According to preliminary experiments, valosin possesses biological effects on the gastrointestinal tract of the dog.
