The thromboxane receptor (TP) is a protein on the surface of cells in the endothelium of blood vessels and in the placenta which interacts with the eicosanoid lipid thromboxane. It is a G-protein coupled receptor coupled to the G protein Gq.[1]

Gene

The gene responsible for the thromboxane receptor, TBXA2R is found on chromosome 19 and spans 15 kilobases. Thromboxane is a potent stimulator for platelet aggregation and clot formation and also plays a role in vascular tone. [2] The thromboxane receptor is a member of the family of G protein-coupled receptors. Mutation of the receptor can lead to a bleeding disorder.
