Specificity
This antibody recognises cyclic AMP-dependent transcription factor ATF1, also known as activating transcription factor 1 or protein TREB36.ATF1 is a protein belonging to the ATF subfamily of the bZIP (basic-region leucine zipper) family involved in the regulation of the expression of genes involved in several cellular processes including cell growth and survival. The ATF1 protein is phosphorylated at serine 63 in its kinase-inducible domain by several serine/threonine kinases, including cAMP-dependent protein kinase A and cyclin-dependent kinase 3 (CDK3). Phosphorylation of ATF1 at serine 63 enhances its transactivation and transcriptional activity, thereby enhancing cell transformation.
