Transcription factor that acts as a key player in the regulatory circuit that integrates secondary metabolism and cellular response to oxidative stress (PubMed:21808056). Regulates the genes involved in development, stress response, and secondary metabolism through direct binding to their promoters (PubMed:23281343, PubMed:28926946). Particularly involved in the resistance to oxidative stress in asexual conidiospores (PubMed:23281343). Binds aflatoxin gene promoters carrying the cAMP-response element (CRE1) under aflatoxin-inducing conditions (PubMed:21808056, PubMed:23281343). Leads to a decrease in aflatoxin enzyme levels, down-regulation of aflatoxin accumulation, and impaired conidiospore development (PubMed:28926946). Belongs to the bZIP family. ATF subfamily.
