Neurotensin receptor type 2 is a protein that in humans is encoded by the NTSR2 gene.

Function

The protein encoded by this gene belongs to the G protein-coupled receptor family that activates a phosphatidylinositol-calcium second messenger system. Binding and pharmacological studies demonstrate that this receptor binds Neurotensin (NT) as well as several other ligands already described for Neurotensin receptor 1. NT function is known to be a neuromodulator of dopamine and has hypothermic and analgesic properties in the brain and some peripheral organ function as well. NTS2 is found mostly in the brain through Northern-blot analysis.Unlike NTS1, NTS2 has a low affinity with NT and a high sensitivity to levocabastine, an antihistamine, which competes with NT for binding.
