MFS transporter; part of the gene cluster that mediates the biosynthesis of dihydroxynaphthalene (DHN)-melanin, a bluish-green pigment forming a dark layer in the conidial wall that protects the conidia from UV radiations. Expression is positively regulazed by the cluster-specific transcription factor pfmaF. Does not affect the production of scytalone. Belongs to the major facilitator superfamily. Allantoate permease family.
