Efflux pump; part of the gene cluster that mediates the biosynthesis of the mycotoxins roquefortine C and meleagrin (PubMed:22118684). Expression is decreased in presence of phenylacetic acid (PAA) (PubMed:23776469). Does not affect the biosynthesis of roquefortine C and meleagrin (PubMed:23776469). The indole alkaloid meleagrin was shown to be a good candidate to control c-Met-dependent breast cancer proliferation, migration and invasion (PubMed:26692349). Belongs to the major facilitator superfamily. TCR/Tet family.
