ChemiScreen™ TP Prostanoid Receptor Stable Cell Line

TP 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. Thus, the cell line is an ideal tool for screening for antagonists of interactions between TP and its ligands.
