Efflux pump required for efficient secretion of trichosetin or other secondary metabolies produced by the trichosetin gene cluster (PubMed:28379186). Plays a crucial role in detoxification of the toxic trichosetin in Gibberella fujikuroi cells (PubMed:28379186). Expression is induced by the final product trichosetin and not by the trichosetin cluster-specific transcription acticator TF22 (PubMed:28379186). Resulted in the down-regulation of the three biosynthetic genes from the trisetin cluster and a reduced accumulation of trichosetin (PubMed:28379186). Belongs to the major facilitator superfamily.
