This section provides a summary of the gene/protein's function, expression, and relevance to neurodegenerative diseases.
NTS encodes neurotensin, a 13-amino acid neuropeptide that acts as a neurotransmitter and neuromodulator in the central nervous system. Neurotensin is widely distributed in the brain, with highest concentrations in the hypothalamus, amygdala, and substantia nigra. It modulates dopamine transmission, particularly in the mesolimbic and nigrostriatal pathways. Neurotensin also has roles in thermoregulation, pain perception, appetite control, and gastric motility. Its receptors (NTSR1 and NTSR2) are G protein-coupled receptors that activate multiple signaling pathways including PLC, PKC, and MAPK.
High expression in hypothalamus, amygdala, nucleus accumbens, and substantia nigra. Also expressed in peripheral tissues including small intestine, pancreas, and immune cells. In the brain, neurotensin is often colocalized with dopamine.
