Transcription factor that acts as a key player in the regulatory circuit that integrates secondary metabolism and cellular response to oxidative stress (By similarity). Regulates the genes involved in development and stress response through direct binding to their promoters (PubMed:18448366). Particularly involved in the resistance to oxidative stress in asexual conidiospores (PubMed:18448366). Expression is barely detectable at the basal hyphal growth phase but induced during conidial development (PubMed:18448366). Leads to weak conidia formation on hyperosmotic medium (PubMed:18448366). Belongs to the bZIP family. ATF subfamily.
