Product Specific Information

This antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non phosphorylated ATF2. The final product is generated by affinity chromatography using an ATF2-derived peptide phosphorylated at threonine 71. The peptide sequence is conserved in mouse, rat, chicken and frog. Suggested Western blot positive controls: NIH3T3 + anisomycin, or Jurkat + 10 µg/mL anisomycin for 60 minutes.

Target Information

The 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 interacts with a variety of viral oncoproteins and cellular tumor suppressors and is a target of the SAPK/JNK and p38 MAP kinase signaling pathways. Various forms of cellular stress, including genotoxic agents, inflammatory cytokines and UV irradiation, stimulate the transcriptional activity of ATF-2. Cellular stress activates ATF-2 by phosphorylation of Thr69 and Thr71. Both SAPK and p38 MAPK have been shown to phosphorylate ATF-2 at these sites in vitro and in cells transfected with ATF-2.
