MFS-type transporter; part of the gene cluster that mediates the biosynthesis of calidodehydroaustin, a fungal meroterpenoid. In A.calidoustus, the austinoid gene cluster lies on a contiguous DNA region, while clusters from E.nidulans and P.brasilianum are split in their respective genomes. Genetic rearrangements provoked variability among the clusters and E.nidulans produces the least number of austionoid derivatives with the end products austinol and dehydroaustinol, while P.brasilianum can produce until acetoxydehydroaustin, and A.calidoustus produces the highest number of identified derivatives. Belongs to the major facilitator superfamily. TCR/Tet family.
