 The ligand for NTSR1 is the 13 amino acid peptide, neurotensin (NTS)<ref name="SONT">PMID:23051748</ref>, and the majority of the effects of NTS are mediated through NTSR1<ref name="SONT"/>. NTS has a variety of biological activities including a role in the '''[https://en.wikipedia.org/wiki/Leptin leptin]''' signaling pathways <ref name="Mice">PMID: 20211191</ref>, tumor growth <ref name="cancer">PMID:16887236</ref>, and '''[https://en.wikipedia.org/wiki/Dopamine dopamine]''' regulation <ref name="Schizophrenia">PMID:22596253</ref>. NTSR1 was crystallized bound with a C-terminal portion of its tridecapeptide '''[https://en.wikipedia.org/wiki/Ligand ligand]''', <scene name='72/721548/Neurotensin/7'>NTS(8-13)</scene>. The shortened ligand was used because of oits higher potency and efficacy than its full-length counterpart<ref name="SONT"/>.
 A critical topic in the understanding of GPCRs is the transition from the inactive to active state. This transition is responsible for the [https://en.wikipedia.org/wiki/Signal_transduction transduction] of a signal from the extracellular to the intracellular space. The transition occurs when a ligand, NTS in the case of NTSR1, binds to the receptor causing a [https://en.wikipedia.org/wiki/Conformational_change conformational change] that leads to the activation of the intracellular G protein. Currently, only the structure of the active form of NTSR1 is known, making the transition between the active and inactive states difficult to study.<ref name="SONT"/>
