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:24951443, PubMed:28830793). Expression is positively regulated by the developmental and secondary metabolism regulator veA (PubMed:24951443). Expression is highly increased following piperine exposure (PubMed:28830793). Belongs to the bZIP family. ATF subfamily.
