Description
The Tachykinin receptor 1 (TACR1), also known as Neurokinin 1 receptor (NK1R) or Substance P receptor (SPR) is a G protein coupled receptor found in the central nervous system and peripheral nervous system. The endogenous ligand for this receptor is Substance P, although it has some affinity for other tachykinins. The protein is the product of the TACR1 gene. The protein consists of 407 amino acid residues, and it has a molecular weight of 58.000. Tachykinin receptor 1, as well as the other tachykinin receptors, is made of seven hydrophobic transmembrane(TM) domains with three extracellular and three intracellular loops, an amino-terminus and a cytoplasmic carboxy-terminus. The loops have functional sites, including two cysteines amino acids for a disulfide bridge, Asp-Arg-Tyr, which is responsible for association with arrestin and, Lys/Arg-Lys/Arg-X-X-Lys/Arg, which interacts with G-proteins. The NK1R can be found in both the central and peripheral nervous system. It is present in neurons, brainstem, vascular endothelial cells, muscle, gastrointestinal tracts, genitourinary tract, pulmonary tissue, thyroid gland and different types of immune cells. The binding of SP to NK1R has been associated with the transmission of stress signals and pain, the contraction of smooth muscles and inflammation. NK1R antagonists have also been studied in migraine, emesis and psychiatric disorders.
Immunogen
An amino acid sequence from the middle region of human Neurokinin 1 Receptor (DSSDRYHEQVSAKRK) was used as the immunogen for this NK1R antibody (100% homologous in human, mouse and rat).
Storage
After reconstitution, the NK1R antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20 deg. Celcius or lower. Cycles of freezing and thawing can denaturate the peptide chains of the antibodies and reduce their sensitivity and/or change their affinity. Prepare aliqotes in such a manner so that freeze-thaw cycles are minimized. Avoid repeated freezing and thawing.
Properties
If you buy Antibodies supplied by NJS poly they should be stored frozen at - 24°C for long term storage and for short term at + 5°C.
Additional description
The receptors are ligand binding factors of type 1, 2 or 3 and protein-molecules that receive chemical-signals from outside a cell. When such chemical-signals couple or bind to a receptor, they cause some form of cellular/tissue-response, e.g. a change in the electrical-activity of a cell. In this sense, am olfactory receptor is a protein-molecule that recognizes and responds to endogenous-chemical signals, chemokinesor cytokines e.g. an acetylcholine-receptor recognizes and responds to its endogenous-ligand, acetylcholine. However, sometimes in pharmacology, the term is also used to include other proteins that are drug-targets, such as enzymes, transporters and ion-channels.
