Transcription factor that regulates the expression of the gene cluster that mediates the biosynthesis of asperfuranone, a probable antitumor agent (PubMed:19199437). Expression is positively regulated by the secondary metabolism cross-pathway regulator scpR (PubMed:20952652). Leads to decreased production of asperfuranone (PubMed:19199437). Asperfuranone provides anti-proliferative activity in human non-small cell lung cancer cells (PubMed:20148857).
