ATF1 encodes an activating transcription factor, which belongs to the ATF subfamily and bZIP (basic-region leucine zipper) family. It influences cellular physiologic processes by regulating the expression of downstream target genes, which are related to growth, survival, and other cellular activities. This protein is phosphorylated at serine 63 in its kinase-inducible domain by serine/threonine kinases, cAMP-dependent protein kinase A, calmodulin-dependent protein kinase I/II, mitogen- and stress-activated protein kinase and cyclin-dependent kinase 3 (cdk-3). Its phosphorylation enhances its transactivation and transcriptional activities, and enhances cell transformation. Fusion of ATF1 and FUS on chromosome 16 or EWSR1 on chromosome 22 induced by translocation generates chimeric proteins in angiomatoid fibrous histiocytoma and clear cell sarcoma. ATF1 has a pseudogene on chromosome 6.

Activating transcription factor 1 (ATF1), reviewed by UniProt as cyclic AMP-dependent transcription factor ATF-1, is a bZIP transcription factor that links cAMP/PKA signalling to CRE-dependent gene regulation. Human ATF1 maps to NCBI Gene 466 and reviewed UniProtKB P18846; this record links the verified target to related ABMIUM catalogue products.
Biological function: ATF1 binds cAMP response elements (CREs) in promoters and mediates PKA-responsive transcription. Phosphorylation within its kinase-inducible domain enhances transactivation, supporting stimulus-responsive regulation of gene expression.
