Transcription factor that controls the expression of genes related to the process of conidiation and adherence and regulates biofilm formation (PubMed:26529322). Controls conidiation and adhesion primarily by affecting the expression of the three regulatory genes flbB, stuA and medA (PubMed:26529322). Required for virulence in an egg and a mouse infection model (PubMed:26529322). Interacts with ptaB. Impairs conidiophore formation. Belongs to the FLO8 family.
