Background
ATF3 (Activating Transcription Factor 3) is a 181-amino-acid stress-inducible bZIP transcription factor that binds DNA as homo- or heterodimer, recognized by the consensus TGACGTCA, and acts as a dual-function transcriptional regulator—repressing or activating target genes involved in apoptosis, inflammation, cell-cycle checkpoints, metabolic reprogramming and oncogenesis—rapidily up-regulated in response to hypoxia, DNA damage, cytokines, ER stress or mechanical strain, frequently overexpressed in cancers where it promotes survival, metastasis and chemoresistance yet can also function as a tumor suppressor depending on cellular context, and is subject to tight control via MAPK, NF-κB, p53 and multiple feedback loops, making it a critical node in integrating stress signals and determining cell fate.
