      OverviewHuman Oxytocin Receptor
      Background InformationOxytocin is a cyclic 9 amino acid peptide that differs from vasopressin in 2 amino acids. Despite the close similarities in sequence, oxytocin and vasopressin have different biological activities and bind to distinct G protein-coupled receptors. The oxytocin receptor, OT, couples primarily to Gq/11 to mobilize intracellular calcium. In female reproduction, oxytocin promotes uterine contraction and lactation; oxytocin is the most commonly used drug for induction of labor, whereas an oxytocin antagonist, atosiban, is under investigation to suppress preterm labor. Oxytocin/OT interaction in the CNS also plays an important role in stress, male and female sexual response, and sociality (Gimpl and Fahrenholz, 2001). Chemicon's oxytocin 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 antagonists of oxytocin receptor interactions with oxytocin. The membrane preparations exhibit a Kd of 0.53nM for [125I]-OVTA. With 5.0 ug/well Oxytocin Membrane Prep and 0.5 nM [125I]-OVTA, a greater than 6-fold signal-to-background ratio was obtained.

      Biological Information
      Entrez Gene Number
      Entrez Gene SummaryThe protein encoded by this gene belongs to the G-protein coupled receptor family and acts as a receptor for oxytocin. Its activity is mediated by G proteins which activate a phosphatidylinositol-calcium second messenger system. The oxytocin-oxytocin receptor system plays an important role in the uterus during parturition.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P30559 # Receptor for oxytocin. The activity of this receptor is mediated by G proteins which activate a phosphatidylinositol- calcium second messenger system.
      SIZE: 389 amino acids; 42772 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      SIMILARITY: SwissProt: P30559 ## Belongs to the G-protein coupled receptor 1 family.
      Incubation ConditionsMembranes 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, a GF/C 96-well filter plate is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM HEPES, pH 7.4, 0.5% BSA. 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 Hepes, pH 7.4, 5 mM MgCl2, 1 mM CaCl2, 0.2% BSA, filtered and stored at 4°C
      Radioligand: [125I] OVTA (Perkin Elmer # NEX254)
      Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl , 0.1% BSA, filtered and stored at 4°C.
