ATF7 (Activating Transcription Factor 7) is a gene that encodes a transcription factor involved in regulating cellular responses to stress. As part of the ATF/CREB family, it helps control gene expression related to apoptosis, development, and neuronal survival. ATF7 activity is important for maintaining cellular balance, and its dysregulation has been linked to stress-related conditions such as neurodegenerative diseases and cancer.
