G protein-coupled receptor that plays a role in conidiation and regulation of the biosynthesis of secondary metabolites such as dihydroxynaphthalene (DHN)-melanin, via interaction with the G-protein complex alpha subunit gpaA. Interacts with gpaA. Leads to a strong increase of dihydroxynaphthalene (DHN)-melanin production. Belongs to the G-protein coupled receptor GPR1/git3 family.
