Neurotensin receptor
Encyclopedia
The neurotensin receptors are transmembrane receptors that bind the neurotransmitter
Neurotransmitter
Neurotransmitters are endogenous chemicals that transmit signals from a neuron to a target cell across a synapse. Neurotransmitters are packaged into synaptic vesicles clustered beneath the membrane on the presynaptic side of a synapse, and are released into the synaptic cleft, where they bind to...

 neurotensin
Neurotensin
Neurotensin is a 13 amino acid neuropeptide that is implicated in the regulation of luteinizing hormone and prolactin release and has significant interaction with the dopaminergic system...

. Two of the receptors encoded by the and genes contain seven transmembrane helices and are G protein coupled
G protein-coupled receptor
G protein-coupled receptors , also known as seven-transmembrane domain receptors, 7TM receptors, heptahelical receptors, serpentine receptor, and G protein-linked receptors , comprise a large protein family of transmembrane receptors that sense molecules outside the cell and activate inside signal...

. The third receptor has a single transmembrane domain and is encoded by the gene.

  • SR-48692
    SR-48692
    SR-48692 is a drug which acts as a selective, non-peptide antagonist at the neurotensin receptor NTS1, and was the first non-peptide antagonist developed for this receptor. It is used in scientific research to explore the interaction between neurotensin and other neurotransmitters in the brain, and...
