Neurotensin Receptor 1 (NTR1)

Neurotensin (NT) is an endogenous tridecapeptide neurotransmitter that influences distinct central and peripheral physiological functions in mammals. Central administration of NT modulates dopaminergic transmission and triggers hypothermic and naloxone-insensitive analgesic responses, whereas peripheral effects include hypotension, decrease gastric acid release, potentiation of lipid digestion. NT is widely distributed throughout the CNS. It has been localized to catecholamine-containing neurons. NT initiates its biological action by interacting with two distinct G-protein coupled receptors (NTR1 and NTR2). Recently, a third receptor NTR3 has been identified that is identical to gp95/sortilin and it is not coupled via the G-proteins. All three receptors bind NT through its C-terminal hexapeptide sequence (8 RRPYIL 13). Biologically active NT (NT8-13) has also been shown to interact with the extracellular domain 3 (between TM6-7) of NTR1. NTR1/NTRH/NTSR1/NT1 (mouse/rat 424 aa; human 418 aa, chromosome 20q1; ~84% interspecies sequence homology) is the levocabastine-insensitive, high affinity receptor for NT. It has the typical structure of GPCR: 7 TM domains with extracellular N-terminus and cytoplasmic C-terminus. It is shown to mediate a number of peripheral and central NT responses, including the neuroleptic-like effects of the peptide. It is highly expressed in the brain, small intestine, and other peripheral tissues.\n\nApplications: \nSuitable for use in ELISA and Western Blot. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:1000-1:5000. NTR1 is ~52-55kD in rat brain and it may be differentially glycosylated.\nELISA: 1:100,000 using 50-100ng N2177-20 control peptide/well.\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
