Human Neurotensin receptor 1 assay (NTSR1) from Innoprot provides the analysis of both signalling pathways involving GPCR activation; G protein by Calcium flux and β-arrestin recruitment using Nomad multiplex technology. The primary transduction mechanism involves Gq/G11 family transducers, so we measure Ca2+ flux in combination with β-arrestin recruitment in this assay.
Neurotensin receptor 1 belongs to the large superfamily of G-protein coupled receptors. NTSR1 mediates the multiple functions of neurotensin, such as hypotension, hyperglycemia, hypothermia, antinociception, and regulation of intestinal motility and secretion.
