On je član familije G-protein spregnutih receptora. Prostaciklin, glavni proizvod ciklooksigenaze u makrovaskularnom endotelu, uzrokuje potentnu vazodilataciju i inhibiciju agregacije trombocita putem vezivanja za ovaj receptor.

Transdukcija

Prilikom vezivanja za molekul prostaciklina, receptor konformaciju i aktivira G_s, koji aktivira cAMP i povećava aktivnost proteinske kinaze A (PKA).
