Description
Guanylate cyclase soluble subunit alpha-3 is an enzyme that in humans is encoded by the GUCY1A3 gene. Soluble guanylate cyclase (sGC), a heterodimeric protein consisting of an alpha and a beta subunit, catalyzes the conversion of GTP to the second messenger cGMP and functions as the main receptor for nitric oxide and nitrovasodilator drugs
