BrlA, abaA and wetA are pivotal regulators of conidiophore development and conidium maturation (By similarity). They act individually and together to regulate their own expression and that of numerous other sporulation-specific genes (By similarity). Binds to the sequence 5'-CATTCY-3', where Y is a pyrimidine, making both major- and minor-groove contacts (By similarity). Plays an essential role in the differentiation and functionality of phialides (PubMed:25530311). localizes to the nuclei of phialides and terminal cells of mature conidia (By similarity). completely abolishes conidia formation and leads to the formation of compact white colonies (PubMed:25530311). Produces extremely elongated and immature phialides with defective morphology (PubMed:25530311). Belongs to the TEC1 family.
