Name Thromboxane A2 receptor
Synonyms
  1. Prostanoid TP receptor
  2. TXA2-R
Gene Name TBXA2R
Protein Type Unknown
Biological Properties
General Function Involved in G-protein coupled receptor protein signaling pathway
Specific Function Receptor for thromboxane A2 (TXA2), a potent stimulator of platelet aggregation. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system. In the kidney, the binding of TXA2 to glomerular TP receptors causes intense vasoconstriction. Activates phospholipase C. Isoform 1 activates adenylyl cyclase. Isoform 2 inhibits adenylyl cyclase
