Supplementary information

The ATF2 protein also referred to as ATF-2 or activating transcription factor 2 plays a significant role as a transcription factor in cellular processes. It weighs approximately 75 kDa and is expressed in many tissues with higher levels in the brain heart and skeletal muscle. Functionally ATF2 belongs to the leucine zipper family of proteins facilitating its ability to bind DNA and regulate the expression of genes involved in stress responses development and growth.
Biological function summary

ATF2 takes part in the regulation of gene expression in response to various stimuli. It often forms a complex with other proteins such as c-Jun when binding to the DNA. This complex then influences the transcription of genes that respond to cellular stress and DNA damage. By phosphorylating specific serine residues cellular kinases activate ATF2 which then translocates to the nucleus where it exerts its function.

Pathways

ATF2 integrates into the MAPK and JNK signaling cascades which are important for transmitting stress signals from the cell surface to the nucleus. Through these pathways ATF2 interacts with proteins such as JNK and p38 MAPK modulating the transcription of downstream genes that control cell proliferation apoptosis and differentiation. Its role in these pathways positions ATF2 as a critical node where various signaling inputs merge to influence cellular outcomes.

ATF2 has associations with conditions such as cancer and neurological disorders. Aberrant regulation of ATF2 can contribute to oncogenesis by affecting cell cycle control and apoptosis. For example in melanoma altered ATF2 activity is linked to tumor progression and resistance to apoptosis. Additionally in neurological disorders its interaction with proteins like phospho-c-Jun influences neuronal survival and plasticity implicating ATF2 in pathologies related to neurodegeneration and cognitive dysfunction.

Target data

Transcriptional activator which regulates the transcription of various genes, including those involved in anti-apoptosis, cell growth, and DNA damage response. Dependent on its binding partner, binds to CRE (cAMP response element) consensus sequences (5'-TGACGTCA-3') or to AP-1 (activator protein 1) consensus sequences (5'-TGACTCA-3'). In the nucleus, contributes to global transcription and the DNA damage response, in addition to specific transcriptional activities that are related to cell development, proliferation and death. In the cytoplasm, interacts with and perturbs HK1- and VDAC1-containing complexes at the mitochondrial outer membrane, thereby impairing mitochondrial membrane potential, inducing mitochondrial leakage and promoting cell death. The phosphorylated form (mediated by ATM) plays a role in the DNA damage response and is involved in the ionizing radiation (IR)-induced S phase checkpoint control and in the recruitment of the MRN complex into the IR-induced foci (IRIF). Exhibits histone acetyltransferase (HAT) activity which specifically acetylates histones H2B and H4 in vitro (PubMed : 10821277). In concert with CUL3 and RBX1, promotes the degradation of KAT5 thereby attenuating its ability to acetylate and activate ATM. Can elicit oncogenic or tumor suppressor activities depending on the tissue or cell type.
