Prostacyclin (PGI2) prevents formation of the platelet plug involved in primary hemostasis (a part of blood clot formation) and is an effective vasodilator. Binding to its receptor (IP, PTGIR) (Boie et al. 1994) allows coupling to and activation of the G protein alpha s subunit, which leads to activation of cAMP and increase in protein kinase A (PKA) activity (Schwaner et al. 1995).
