The rabbit small intestine contains neuromedin U-like immunoreactivity (22 pmol/g wet tissue weight) that was resolved into a single major molecular form by reversed-phase HPLC. The primary structure of the peptide was established as: Phe-Pro-Val- Asp-Glu-Glu-Phe-Gln-Ser-Pro10-Phe-Gly-Ser-Arg-Ser-Arg-Gly-Tyr-Phe-Leu20-Phe- Arg-Pro-Arg-Asn.NH2. In rabbit neuromedin U, the Arg16-Arg17 dibasic residue processing site that is found in pig and dog neuromedin U-25 is replaced by Arg-Gly, but this potential monobasic processing site is not utilized by cleavage enzyme(s) in the intestine.
