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). localizes to the nuclei of phialides and terminal cells of mature conidia (By similarity). Expression is positively regulated by stuA through direct binding of stuA to the abaA promoter region (PubMed:26283234). Belongs to the TEC1 family.
