The neurotensin receptors are transmembrane receptors that bind the neurotransmitter neurotensin.[1][2] Two of the receptors encoded by the NTSR1 and NTSR2 genes contain seven transmembrane helices and are G protein coupled. The third receptor has a single transmembrane domain and is encoded by the SORT1 gene.
