Activating Transcription Factor 4 (ATF4) is a multifunctional transcription regulatory protein in the basic leucine zipper (bZIP) superfamily. ATF4 can be expressed in most if not all mammalian cell types, and it can participate in a variety of cellular responses to specific environmental stresses, intracellular derangements, or growth factors. Because ATF4 is involved in a wide range of biological processes, its roles in human health and disease are not yet fully understood. Much of our current knowledge about ATF4 comes
