Transcription factor that regulates the expression of the gene cluster that mediates the biosynthesis of yanuthone D, a fungal isoprenoid epoxycyclohexenone that acts as an antibiotic against fungi and bacteria (PubMed:24684908). Leads to significant down-regulation of the yanuthone D gene clister and losses the ability to produce yanuthones D and E (PubMed:24684908). Yanuthone D is an antibiotic against Candida albicans, methicillin-resistant Staphylococcus aureus (MRSA), and vancomycin-resistant Enterococcus (PubMed:11031048).
