| Introduction | 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. Mutations of these sites result in the loss of stress-induced transcription by ATF-2. In addition, mutations at these sites reduce the ability of E1A and Rb to stimulate gene expression via ATF-2.ATF-7 is another member of the ATF/CREB family of leucine zipper proteins. Similarly, Thr51 and Thr53 (corresponding to Thr69 and Thr71 of ATF-2, respectively) can be phosphorylated under different conditions. |

| Immunogen | Synthetic phosphopeptide corresponding to residues surrounding Thr71 of human ATF-2. |
| Source/Purification | Antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr71 of human ATF-2. Antibodies are purified by protein A and peptide affinity chromatography. |
| Usage | |
|---|---|
| Application | WB, IP, IF, IHC, FC |
| Dilutions | Western Blot (1:1000); Immunoprecipitation (1:250) |
| MW(KDa) | 65, 75 |
| Reactivity | Human, Mouse, Rat, Monkey |
| Sensitivity | Endogenous |
| Specificity | It detects endogenous levels of ATF-2 and ATF-7 only when phosphorylated at threonine 71 and threonine 53, respectively. This antibody does not cross-react with phosphorylated c-Jun, CREB, or other transcription factors. It recognizes Thr69/Thr71 dually phosphorylated ATF-2, Thr51/Thr53 dually phosphorylated ATF-7, Thr71 singly phosphorylated ATF-2, and Thr53 singly phosphorylated ATF-7 equally well. |
