MFS-type transporter; part of the gene cluster that mediates the biosynthesis of azaterrilone A and other azaphilones, a class of fungal metabolites characterized by a highly oxygenated pyrano-quinone bicyclic core and exhibiting a broad range of bioactivities. Expression is positively regulated by the azaterrilone A cluster-specific transcription factor tazR. Belongs to the major facilitator superfamily. CAR1 family.
