Background: The human prostaglandin I2 receptor IP1 (or PTGIR) mediates the actions of prostaglandin I2 (PGI2 or prostacyclin), which is a labile metabolite of arachidonic acid produced in concert with the bis-enoic prostaglandins via the cyclooxygenase pathway. PGI2 plays a major physiologic role as a strong mediator of vasodilation and inhibitor or platelet activation, and is an antithrombotic agent in vivo and mediates inflammation and pain. PGI2 derived from COX2 plays a critical role in regulating the release of rennin and consequently in renovascular hypertension.
