Gallery: Phospho-ATF-2 (Thr71) (11G2) Rabbit mAb (Biotinylated) #4036
Phospho-ATF-2 (Thr71) (11G2) Rabbit mAb (Biotinylated) detects endogenous levels of ATF-2 only when phosphorylated at Thr71. 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.
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr71 of human ATF2 protein.
This Cell Signaling Technology (CST) antibody is conjugated to biotin under optimal conditions. The unconjugated Phospho-ATF-2 (Thr71) (11G2) Rabbit mAb #5112 reacts with human, mouse, rat and monkey phospho-ATF-2 protein. CST expects that Phospho-ATF-2 (Thr71) (11G2) Rabbit mAb (Biotinylated) will also recognize phospho-ATF-2 in these species.
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).
