Background Information

TBXA2R, also named as thromboxane A2 receptor, TXA2-R and Prostanoid TP receptor, belongs to G-protein coupled receptor 1 family. Thromboxane A2 receptor is a key molecule in hemostasis as its abnormality leads to bleeding disorders. The TXA2-R receptor is linked via a guanine nucleotide-binding protein (G protein) to phospholipase C (PLC), which hydrolyses phosphoinositides to the two potent stimulatory second messengers inositol 1,4,5-triphosphate (IP3) and diacylglycerol. IP3 causes increases in cytoplasmic free calcium and diacylglycerol causes activation of protein kinase C. In the kidney, the binding of TXA2-R to glomerular TP receptors causes intense vasoconstriction. The two isoforms expressed in cultured cells show similar ligand binding characteristics and phospholipase C (PLC) activation but oppositely regulate adenylyl cyclase activity (PMID: 8613548).
