Previous GeneCards Identifiers 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]
GeneCards Summary for NTSR2 Gene
NTSR2 (Neurotensin Receptor 2) is a Protein Coding gene. Among its related pathways are Peptide ligand-binding receptors and Signaling by GPCR. Gene Ontology (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 NTSR1.
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).
