MFS-type transporter; part of the gene cluster that mediates the biosynthesis of pyranterreones, a family of antioxidative compounds (PubMed:32077283). Directly involved in the secretion of pyranterreones (PubMed:32077283). Expression is positively regulated by the cluster-specific transcription factor pytR. Blocks the secretions of pyranterreones. Belongs to the major facilitator superfamily. Monocarboxylate porter (TC 2.A.1.13) family.
