      DescriptionChemiSCREEN™ Membrane Preparation Recombinant Human EP2 Prostanoid Receptor
      OverviewFull-length human PTGER2 cDNA encoding EP2
      Background InformationProstanoids bind to a family of 8 GPCRs to exert their biological effects (Narumiya and FitzGerald, 2001). The protanoid PGE2 causes pain, vasodilation, immunosuppression of T cells, bone resorption and promotion of carcinogenesis. Four related GPCRs, EP1, EP2, EP3 and EP4, each bind to PGE2, but the different G protein coupling status of each receptor leads to distinct biological effects. EP2 couples primarily to Gs to increase intracellular cAMP levels. Mice deficient in EP2 receptor showed impaired ovulation and fertilization, salt-sensitive hypertension (Kennedy et al., 1999). It has been shown that EP2 receptors are also involved in cancer associated immunodeficiency. Thus, genetic knockout of the EP2 receptor reduced tumor growth and prolonged survival in mice that had undergone isograft injection of MC26 or Lewis lung carcinoma cells (Yang et al., 2003). Millipore's EP2 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 EP2. The membrane preparations exhibit a Kd of 14.52 nM for [3H]-PGE2. With 7.5 nM [3H]-PGE2, 10µg/well EP2 Membrane Prep typically yields greater than 3-fold signal-to-background ratio.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P43116 # Receptor for prostaglandin E2 (PGE2). The activity of this receptor is mediated by G(s) proteins that stimulate adenylate cyclase. The subsequent raise in intracellular cAMP is responsible for the relaxing effect of this receptor on smooth muscle.
      SIZE: 358 amino acids; 39761 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      TISSUE SPECIFICITY: Placenta and lung.
      SIMILARITY: SwissProt: P43116 ## 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, 500mM NaCl. 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, filtered and stored at 4°C.
      Radioligand: [3H]-PGE2 (Perkin Elmer#: NET-428)
      Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl, filtered and stored at 4°C.
