Neuromedin N is a neuropeptide derived from the same precursor polypeptide as neurotensin, and with similar but subtly distinct expression and effects.[2][3][4][5][6][7] Composed of the amino acid sequence Lys-Ile-Pro-Tyr-Ile-Leu, neuromedin N is homologous to neurotensin, both of whose sequences are found on the pro neurotensin/neuromedin N precursor C-terminus.[8][9] Both sequences of neuromedin N as well as neurotensin are flanked by Lys-Arg amino acids, which comprise a consensus sequence for the endoprotease proprotein convertase.[8] Neuromedin N is primarily synthesized in the neural and intestinal tissues of mammals; in studies performed in mice, neuromedin N's physiological effects were shown to include hypothermia and analgesia, arising from the peptide's ligand association to and interaction with neurotensin type 2 (NTS2) G protein-coupled receptors.[8][10]
