MFS transporter; part of the gene cluster that mediates the biosynthesis of the antitumor cytotoxic peptidyl alkaloids fumiquinazolines that confer a dual-usage capability to defend against phagocytes in the environment and animal hosts (PubMed:20804163, PubMed:24612080, PubMed:33705521). Probably involved in fumiquinazolines metabolism and transport (PubMed:24612080). Expression is positively regulated by brlA, a conidiation-specific transcription factor involved in the early stage of asexual development and necessary for conidiophore formation (PubMed:24612080). Seems not to affect fumiquinazolines production (PubMed:24612080). Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family.
