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 a pivotal role in conidiation by regulating cell cycle pathways and other conidiation-related genes (PubMed:24039821). localizes to the nuclei of phialides and terminal cells of mature conidia (PubMed:24039821). Expression is positively regulated by flbD (PubMed:25277408). Leads to abnormally shaped phialides and abolishes production of conidia (PubMed:24039821). Belongs to the TEC1 family. Extended N-terminus.
