背景信息

**Background of Recombinant ATF7 Protein**

Activating Transcription Factor 7 (ATF7), a member of the ATF/CREB (cAMP-response element-binding protein) family, is a transcription factor involved in regulating stress-responsive gene expression and cellular adaptation to environmental changes. It shares structural homology with other ATF proteins, featuring a basic leucine zipper (bZIP) domain that enables DNA binding and dimerization with partners like c-Jun or other ATF members. ATF7 is ubiquitously expressed, with roles in diverse biological processes, including cell proliferation, differentiation, immune responses, and tumorigenesis.

Under basal conditions, ATF7 often represses target genes by recruiting histone H3K9 dimethyltransferases (e.g., G9a) to maintain heterochromatin states. Upon stress stimuli (e.g., UV radiation, cytokines, or oxidative stress), ATF7 undergoes post-translational modifications, such as phosphorylation by stress-activated kinases (e.g., p38 MAPK), leading to its activation. This triggers dissociation from chromatin modifiers and recruitment of co-activators, enabling transcriptional activation of stress-response genes like *IL-6* or *TNF-α*. Dysregulation of ATF7 is linked to inflammatory diseases, cancer progression, and neurological disorders.

Recombinant ATF7 protein is engineered for research to study its molecular interactions, DNA-binding properties, and regulatory mechanisms. Produced via bacterial or mammalian expression systems, it often includes tags (e.g., His-tag) for purification. Studies using recombinant ATF7 have elucidated its role in epigenetic regulation, stress signaling pathways, and cross-talk with oncogenic or immune-related pathways. Its application extends to drug screening, structural analysis, and exploring therapeutic strategies targeting ATF7-mediated transcription in diseases.

In summary, recombinant ATF7 serves as a critical tool for decoding its dual regulatory functions and developing interventions for ATF7-associated pathologies.
