Neuromedin N (NMN)

Neuromedin N is a neuropeptide derived from the same precursor polypeptide as neurotensin, and with similar but subtly distinct expression and effects. Neurotensin and neuromedin N are two biologically active related peptides which are encoded in the same precursor molecule. In the rat, the precursor consists of a 169-residue polypeptide containing in its C-terminal region one copy each of neurotensin and neuromedin N. Of these sites, the three that are closest to the C-terminus flank and separate neurotensin and neuromedin N. The fourth precedes a neuromedin N-like sequence. The present studies were aimed at determining the extent to which each of these four dibasic sites is cleaved and at identifying and quantifying the intermediate and mature products to which this cleavage gives rise in extracts from whole rat brain, hippocampus and globus pallidus.
