External Ids for NTSR2 Gene
The protein encoded by this gene belongs to the G protein-coupled receptor family that activate a phosphatidylinositol-calcium second messenger system. Binding and pharmacological studies demonstrate that this receptor binds neurotensin as well as several other ligands already described for neurotensin NT1 receptor. However, unlike NT1 receptor, this gene recognizes, with high affinity, levocabastine, a histamine H1 receptor antagonist previously shown to compete with neurotensin for low-affinity binding sites in brain. These activities suggest that this receptor may be of physiological importance and that a natural agonist for the receptor may exist. [provided by RefSeq, Jul 2008]

NTSR2 (Neurotensin Receptor 2) is a Protein Coding gene. Diseases associated with NTSR2 include alcohol dependence. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include G-protein coupled receptor activity and G-protein coupled neurotensin receptor activity. An important paralog of this gene is GPR39.
UniProtKB/Swiss-Prot for NTSR2 Gene
Receptor for the tridecapeptide neurotensin. It is associated with G proteins that activate a phosphatidylinositol-calcium second messenger system
Neurotensin (NT) is a brain and gastrointestinal peptide that acts on three subtypes of neurotensin receptors; the G-protein-coupled receptors NTS1 (high affinity) and NTS2 (low affinity) and the single transmembrane receptor NTS3 (Sortilin 1). These receptors have many central and peripheral actions including modulation of dopaminergic transmission in nigro-striatal and mesocorticolimbic pathways, modulation of the digestive tract and hypothermic and analgesic effects. NTS1 is distributed widely throughout the brain and gastrointestinal tract, whilst NTS2 is confined to areas of the brain involved in the descending control of nociception, including the periaqueductal gray and dorsal raphe. The human genes encoding NTS1 and NTS2 receptors are located on chromosomes 20q13 and 2p25.1 respectively.
