Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, F=Flow Cytometry
Specificity / Sensitivity
Phospho-ATF-2 (Thr71) (11G2) Rabbit mAb detects endogenous levels of ATF-2 only when phosphorylated at threonine 71. This antibody does not cross-react with phosphorylated c-Jun, CREB or other transcription factors. It recognizes both Thr69/Thr71 dually phosphorylated ATF-2 and Thr71 singly phosphorylated ATF-2 equally well.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr71 of human ATF2.
Western blot analysis of extracts from untreated or UV-treated COS cells, NIH/3T3 cells and C6 cells, using Phospho-ATF-2 (Thr71) (11G2) Rabbit mAb (upper), or ATF-2 (20F1) Rabbit mAb #9226 (lower).
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 (1). 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 (2-4). 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 (2-4). 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 (2-4). In addition, mutations at these sites reduce the ability of E1A and Rb to stimulate gene expression via ATF-2 (2).
