AbaA and wetA are pivotal regulators of conidiophore development and conidium maturation. They act individually and together to regulate their own expression and that of numerous other sporulation-specific genes. Binds to the sequence 5'-CATTCY-3', where Y is a pyrimidine, making both major- and minor-groove contacts. Plays a pivotal role in conidiation by regulating cell cycle pathways and other conidiation-related genes
