      DescriptionChemiSCREEN™ Membrane Preparation Recombinant Human 5-HT1B Serotonin Receptor
      OverviewFull-length human HTR1B cDNA encoding the 5-HT1B Serotonin Receptor
      Background Information5-Hydroxytryptamine (5-HT, also commonly known as serotonin) is synthesized in enterochromaffin cells in the intestine and in serotonergic nerve terminals. In the periphery, 5-HT mediates gastrointestinal motility, platelet aggregation, and contraction of blood vessels. Many functions of the central nervous system are influenced by 5-HT, including sleep, motor activity, sensory perception, arousal and appetite. A family of 12 GPCRs and one ion channel mediate the biological effects of 5-HT (Hoyer et al., 1994). The 5-HT1B receptor (also known as 5-HT1Dβ) is expressed presynaptically on serotonergic neurons and postsynaptically on non-serotonergic neurons, and it regulates release of 5-HT and acetylcholine. Several brain regions, including globus pallidus, substantia nigra and dorsal subiculum, highly express HT1B. 5-HT1B has been implicated in the physiology of aggression, depression, migraine, anxiety and reward for drugs of abuse (Sari, 2004). 5-HT1B interacts with p11, which increases cell surface expression and function of 5-HT1B (Svenningsson et al., 2006). Millipore's 5-HT1B membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening of agonists and antagonists of 5-HT1B. The membrane preparations exhibit a Kd of 10.5 nM for [3H]-GR125743. With 7 nM [3H]-GR125743, 10μg/well 5-HT1B Membrane Prep typically yields greater than 8-fold signal-to-background ratio.

      Biological Information
      Entrez Gene Number
      Entrez Gene SummaryThe neurotransmitter serotonin (5-hydroxytryptamine; 5-HT) exerts a wide variety of physiologic functions through a multiplicity of receptors and may be involved in human neuropsychiatric disorders such as anxiety, depression, or migraine. These receptors consist of 4 main groups, 5-HT-1, 5-HT-2, 5-HT-3, and 5-HT4, subdivided into several distinct subtypes on the basis of their pharmacologic characteristics, coupling to intracellular second messengers, and distribution within the nervous system (Zifa and Fillion, 1992 [PubMed 1359584]). The serotonergic receptors belong to the multigene family of receptors coupled to guanine nucleotide-binding proteins.[supplied by OMIM]

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P28222 # This is one of the several different receptors for 5- hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. The activity of this receptor is mediated by G proteins that inhibit adenylate cyclase activity.
      SIZE: 390 amino acids; 43568 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      PTM: Phosphorylated. Desensitization of the receptor may be mediated by its phosphorylation. & Palmitoylated.
      SIMILARITY: SwissProt: P28222 ## Belongs to the G-protein coupled receptor 1 family.
      Incubation ConditionsRECOMMENDED ASSAY CONDITIONS: Membranes are mixed with radioactive ligand and unlabeled competitor (see Figures 1 and 2 for concentrations tested) in binding buffer in a nonbinding 96-well plate, and incubated for 1-2 h. Prior to filtration, an FC 96-well harvest plate (Millipore cat. # MAHF C1H) is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM Tris, pH 7.4. Binding reaction is transferred to the filter plate, and washed 3 times (1 mL per well per wash) with Wash Buffer. The plate is dried and counted.

      Binding buffer: 50 mM Tris, pH 7.4, 10 mM MgCl2, 1 mM EDTA, filtered and stored at 4°C

      Radioligand: [3H]-GR125743. (Amersham #:TRK-1046 )

      Wash Buffer: 50 mM Tris, pH 7.4, filtered and stored at 4°C.

      One package contains enough membranes for at least 200 assays (units), where a unit is the amount of membrane that will yield greater than 8-fold signal:background with 3H labeled GR125743 at 7 nM
