BrlA, abaA and wetA are pivotal regulators of conidiophore development and conidium maturation (PubMed:24113825). They act individually and together to regulate their own expression and that of numerous other sporulation-specific genes (By similarity). Binds promoters of target genes at brlA response elements (BREs) containing the conserved sequence 5'-(C/A)(A/G)AGGG(G/A)-3' (By similarity). Regulates the expression levels of seven secondary metabolism gene clusters including a down-regulated cluster putatively involved in the biosynthesis of the mycotoxins roquefortine C and meleagrin (PubMed:24113825). Negatively regulates the expression of cellulase genes (PubMed:24113825). Expression is controlled by the casein kinase CK2 (PubMed:24613994). Blocks conidia formation and increases hyphal branching (PubMed:24113825). Affects the expression of seven secondary metabolism gene clusters including those in the biosynthesis of roquefortine C and meleagrin, and up-regulates the expression levels of most cellulase genes (PubMed:24113825).
