Transcription factor that binds the promoters of genes involved in biofilm formation, which include several key adhesion genes, and recruits MCM1 to these sites. Plays an important role in hyphal growth and virulence. Promotes conversion of opaque cells to white phase, but needs existence of EFG1, a key regulator required for maintenance of the white state. Interacts with MCM1. Stabilizes the opaque phase.
