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.

Ligands

Agonists

Peptide
  • Beta-lactotensin (NTS2)[3]
  • JMV-449
  • Neurotensin
  • Neuromedin N (NTS1 selective)
  • PD-149,163 (NTS1 selective, reduced amide bond 8-13 fragment of neurotensin)
Non-peptide
  • Partial agonists derived from SR-48692[4]

Antagonists

Biophysical Investigation

Unusually for GPCRs, NTS1 can be expressed in an active form in the bacteria E. coli.[7] It can be purified and analysed in vitro and has been analysed by a number of biophysical techniques such as surface plasmon resonance,[8] FRET[9] and cryo-electron microscopy.[10]
