Agonist Comments
The sequence of neurotensin is identical for all mammalian species.

Xenopsin is a Xenopus laevis peptide similar to neurotensin [1].

Neuromedin N is expressed with neurotensin from the precursor [10].

Contulakin-G is an analogue of neurotensin from Conus geographus venum [9].

Levocabastine was originally developed as an antagonist of histamine receptor H1 [21].

JMV431 is a pseudo-peptide neurotensin analogue [12].
Antagonist Comments
SR48692, a NTS1 antagonist acts as an agonist both on human and mouse NTS2 receptors [4,30].
Primary Transduction Mechanisms Click here for help
Transducer Effector/Response
Gq/G11 family Phospholipase C stimulation
Comments:  The injection of cRNAs corresponding to the mouse NTS2 receptor into Xenopus oocytes leads to a protein expressed at the oocyte surface that activates chloride currents upon neurotensin stimulation.
