The activating transcription factor ATF-2 (also called CRE-BP1) binds to both AP-1 and CRE DNA response elements and is a member of the ATF/CREB family of leucine zipper proteins. ATF-2 has been implicated in the transcriptional regulation of a number of genes including cytokines, cell cycle control and apoptosis. Various forms of cellular stress, including inflammatory cytokines and UV irradiation, stimulate the transcriptional activity of ATF-2. Stress induced ATF-dependent transcription is dependent on phosphorylation of ATF. Serine 490 and serine 498 are novel phosphorylation sites on ATF that have recently been identified. In addition, ATF2 is particularly abundant in the brain and the ATF2 family of transcription factors is considered important substrates of signals upstream of the activation of genes associated with neuronal growth and differentiation. ATF expression has also been linked to the depression in humans.

A synthetic phosphopeptide corresponding to amino acids residues surrounding the human phospho Ser490/498 of ATF2 was used as immunogen. The antibody was purified by sequential chromatography on phospho- and non-phosphopeptide affinity columns.

Application Notes
Specific for ~74 kDa ATF2 protein phosphorylated at Ser490/498. The antibody also recognizes the phosphorylated ~54 kDa splice form of ATF2. Antibody dilutions and tissue load should be based on tissue type and expected phosphorylation state expected expression level.
