MFS-type transporter; part of the gene cluster that mediates the biosynthesis of fumigermin that inhibits germination of spores of the inducing S.rapamycinicus, and thus helps the fungus to defend resources in the shared habitat against a bacterial competitor (PubMed:32083553). May be involved in the secretion of fumigermin (Probable). Expression is up-regulated during co-cultivation of A.fumigatus with Streptomyces rapamycinicus that triggersthe production of the polyketide fumigermin during the bacterial-fungal interaction. Belongs to the major facilitator superfamily. Monocarboxylate porter (TC 2.A.1.13) family.
