      Recombinant Human TBXA2R (TP) Thromboxane Receptor
      OverviewHuman Full-length human TBXA2R cDNA encoding the TP short form (TPα)
      Background InformationTP receptors (Thromboxane A2 receptors) are widely distributed among different organ systems and have been localized on both cell membranes and intracellular structures. TP receptors belong to G protein-coupled receptor family (Hirata et al., 1991). Activation of TP receptors induces platelet aggregation, vascular and respiratory smooth muscle constriction, and enhances mitogenic responses of vascular smooth muscle cells that are stimulated by growth factors (Ali et al, 1993; Hanasaki et al., 1990). The human TP receptor is encoded by a single gene that is alternatively spliced at the carboxyl terminus, resulting in two isoforms, TPα (343 residues) and TPβ (407 residues). Both isoforms couple to Gq pathway, but couple oppositely to adenylate cyclase. The cDNA encoding human TPα has been stablely expressed in the Chem-1 host, which supports high levels of recombinant receptor expression on the cell surface and contains high levels of the promiscuous G protein Gα15 to couple the receptor to the calcium signaling pathway. The membrane preparations exhibit a Kd of 9.19 nM for [3H]-SQ 29548. With 10 nM [3H]-SQ 29548, 10 ug/well TP Membrane Prep yields greater than 5-fold signal-to-background ratio.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: P21731 # Receptor for thromboxane A2 (TXA2), a potent stimulator of platelet aggregation. The activity of this receptor is mediated by a G-protein that activate a phosphatidylinositol-calcium second messenger system. In the kidney, the binding of TXA2 to glomerular TP receptors causes intense vasoconstriction.
      SIZE: 369 amino acids; 40092 Da
      SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
      DISEASE:SwissProt: P21731 # Defects in TBXA2R are the cause of a dominantly inherited bleeding disorder [MIM:188070].
      SIMILARITY: SwissProt: P21731 ## 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 50 mM 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: [3H]-SQ 29548 (Perkin Elmer # NET936)
      Wash Buffer: 50 mM Hepes, pH 7.4, 500 mM NaCl , 0.1% BSA, filtered and stored at 4°C.
