MFS-type transporter; part of the gene cluster that mediates the biosynthesis of astellolides, drimane-type sesquiterpene esters that show antimicrobial, anti-inflammatory, and anti-tumor activities (PubMed:27628599). Seems not to be involved in astellolides translocation (PubMed:27628599). Expression is regulated by the secondary metabolite regulator cclA. Does not affect the production of astellolides. Belongs to the major facilitator superfamily. TCR/Tet family.
