Neuromedin N
Also known as NMN
Neuromedin N is a 6-amino acid peptide co-synthesized with neurotensin, acting on neurotensin receptors to modulate dopaminergic and other neural systems.
- Length
- 6 amino acids
- Half-life
- Not well characterised, presumed very short
- Mechanism
- Co-released with neurotensin and binds to neurotensin receptors (NTR1, NTR2), acting as a functional neurotensin agonist.
- Studied in
- Research applications include its use as a tool to study the neurotensin system, particularly its involvement in dopamine pathway modulation, thermoregulation, and analgesia.
About Neuromedin N
Neuromedin N is a hexapeptide that is derived from the same precursor protein as the larger neuropeptide, neurotensin. Both peptides are co-synthesized and co-released from neurons, particularly in brain regions associated with the dopamine system, such as the substantia nigra and ventral tegmental area.
In a laboratory context, Neuromedin N is studied for its ability to mimic many of the central effects of neurotensin. It binds to and activates neurotensin receptors (NTRs) and is used to investigate neurotensin-mediated signalling. Key research areas include its modulatory effects on reward and motivation pathways, its role in thermoregulation, and its analgesic properties.
Laboratory notes
- As it is encoded on the same precursor, its physiological effects are often studied in parallel with neurotensin.
- Due to its small size and peptidic nature, it is likely subject to rapid enzymatic degradation in biological systems.
- Reconstitute in sterile water or buffer; ensure pH is suitable to maintain peptide integrity and consider using low-protein binding labware.

Questions about Neuromedin N
How is Neuromedin N related to neurotensin?
It is a smaller peptide derived from the same proneurotensin/neuromedin N precursor and is released along with neurotensin.
Does Neuromedin N have its own receptor?
No, it does not have a unique receptor. It exerts its biological effects by binding to neurotensin receptors (NTR1 and NTR2).
What is a major functional system modulated by Neuromedin N?
Through its action on neurotensin receptors, it is a significant modulator of the mesolimbic and nigrostriatal dopamine systems.
Is Neuromedin N for human use?
No. It is supplied strictly for in-vitro laboratory research and is not for human or animal consumption.
