Regulatory Protein Abaa (Abaa), Partial (abaA) Emericella Nidulans Recombinant Protein

BrlA, abaA and wetA are pivotal regulators of conidiophore development and conidium maturation (PubMed:2655931, PubMed:2196567). They act individually and together to regulate their own expression and that of numerous other sporulation-specific gene (PubMed:2655931, PubMed:2823119). Controls temporal and spatial specificity in Aspergillus development (PubMed:2655931, PubMed:7704830). Directs the differentiation of phialides and is continuously required for maintenance of their function (PubMed:2152124). Expression of abaA leads to activation of brlA and wetA, cessation of vegetative growth, and accentuated cellular vacuolization (PubMed:2655931). Binds to the sequence 5'-CATTCY-3', where Y is a pyrimidine, making both major- and minor-groove contacts (PubMed:8139553). Multiple abaA binding sites are present in the cis-acting regulatory regions of several developmentally controlled structural genes as well as those of the upstream regulatory gene brlA, the downstream regulatory gene wetA, and abaA itself (PubMed:8139553).
