Target Name

ATF7

Target Full Name

Cyclic AMP-dependent transcription factor ATF-7

Target Function

Stress-responsive chromatin regulator that plays a role in various biological processes including innate immunological memory, adipocyte differentiation or telomerase regulation. In absence of stress, contributes to the formation of heterochromatin and heterochromatin-like structure by recruiting histone H3K9 tri- and di-methyltransferases thus silencing the transcription of target genes such as STAT1 in adipocytes, or genes involved in innate immunity in macrophages and adipocytes. Stress induces ATF7 phosphorylation that disrupts interactions with histone methyltransferase and enhances the association with coactivators containing histone acetyltransferase and/or histone demethylase, leading to disruption of the heterochromatin-like structure and subsequently transcriptional activation. In response to TNF-alpha, which is induced by various stresses, phosphorylated ATF7 and telomerase are released from telomeres leading to telomere shortening. Plays also a role in maintaining epithelial regenerative capacity and protecting against cell death during intestinal epithelial damage and repair.; Acts as a dominant repressor of the E-selectin/NF-ELAM1/delta-A promoter.; Acts as a negative regulator, inhibiting both ATF2 and ATF7 transcriptional activities. It may exert these effects by sequestrating in the cytoplasm the Thr-53 phosphorylating kinase, preventing activation.

Target Background

Enables several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; mitogen-activated protein kinase binding activity; and transcription coactivator binding activity. Involved in negative regulation of transcription by RNA polymerase II and positive regulation of transcription by RNA polymerase II. Located in nucleoplasm. Biomarker of colorectal cancer.
