Transcription factor that regulates the expression of the gene cluster that mediates the biosynthesis of aurovertins, fungal polyketides that exhibit potent inhibition of adenosine triphosphate synthase (PubMed:26340065). Blocks the expression of the aurovertin gene cluster and impairs the production of aurovertins (PubMed:26340065). Belongs to the POU transcription factor family. Class-3 subfamily.
