Transcription factor that may coregulate the expression of the gene cluster that mediates the biosynthesis of the lipopeptide antibiotics leucinostatins that show extensive biological activities, including antimalarial, antiviral, antibacterial, antifungal, and antitumor activities, as well as phytotoxic. Expression is negatively regulated by the leucinostatins biosynthesis cluster-specific transcription regulator lcsF.
