Biological function summary

ATF1 participates in the regulation of various cellular processes including proliferation differentiation and response to stress signals. It can form heterodimers with other members of the CREB family such as CREB1 allowing it to regulate diverse gene sets. These complexes enhance the DNA-binding affinity and transcriptional activity directed by CRE sites influencing cellular homeostasis and adaptation. Additionally post-translational modifications such as phosphorylation by protein kinases modulate ATF1 activity and stability.

Pathways

ATF1 integrates into the cAMP signaling pathway and the MAPK/ERK pathway. In the cAMP signaling pathway ATF1 responds to hormonal signals that activate adenylate cyclase resulting in increased levels of cAMP and subsequent activation of Protein Kinase A (PKA). PKA phosphorylates ATF1 increasing its transcriptional activity. In the MAPK/ERK pathway ATF1 links to the activation of mitogen-activated protein kinases which modulate gene expression related to cell growth and survival. This interaction also involves other proteins such as CREB and ATF2 highlighting a network of transcription factors that co-regulate gene expression.
