Function
Transcription factor required for hyphal growth, biofilm formation, and virulence. Promotes formation of both conventional and pheromone-stimulated biofilms. Binds and recruits HDA1 to promoters of hypha-specific genes in a rapamycin-dependent manner. Involved in the switch between two heritable states, the white and opaque states. These two cell types differ in many characteristics, including cell structure, mating competence, and virulence. Each state is heritable for many generations, and switching between states occurs stochastically at low frequency.
