ATF3 also known as Activating Transcription Factor 3 functions primarily as a stress-responsive transcription factor. This protein has a molecular weight of about 21 kDa and is part of the ATF/CREB family of transcription factors. ATF3 is expressed in various tissues and is known for its role in stress response and regulation of gene expression. The expression levels change in response to cellular stress and it may interact with several other transcription factors to modulate gene expression profiles.
Biological function summary
ATF3 acts as a regulator of cellular stress responses and can influence cell cycle arrest and apoptosis. It does not form a large complex but interacts with diverse partners to execute its functions. Studies often use HCT116 cells to investigate ATF3's role where it can serve as a marker of cellular stress and inflammation. The protein regulates genes involved in maintaining homeostasis in stressed cells.
Pathways
ATF3 is involved in stress response and apoptotic pathways. In the context of apoptosis ATF3 interacts with proteins like p53 and Jun which are important for inducing cell cycle arrest and programmed cell death. In stress response pathways ATF3 modifies transcriptional activity in reaction to various stress signals providing a checkpoint for damaged cells before repairing or entering programmed death.
ATF3 relates to cancer and cardiovascular diseases. In cancer abnormal expression of ATF3 can influence tumor growth and metastasis often acting through its interactions with proteins like NF-kB. Additionally in cardiovascular disorders ATF3's role in regulating stress responses underpins its involvement in conditions linked to inflammation and atherosclerosis again with NF-kB signaling being a relevant pathway of interaction. Researchers continue to study ATF3 to uncover therapeutic targets for these and other diseases.
