Guanylate cyclase soluble subunit alpha-3 is an enzyme that in humans is encoded by the GUCY1A3 gene.^[5][6]

Function

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.^[6] Mutations in this gene have been associated to cases of myocardial infarction (10.1038/nature12722).
