Description
ATF-2 (activating transcription factor-2, CRE-BP1) is a transcription factor that binds the cAMP response element (CRE) and AP-1 response element and is abundantly expressed in the brain. Various forms of cellular stress, including genotoxic agents, inflammatory cytokines, and UV irradiation, stimulate the transcriptional activity of ATF-2 (2). SAPK and p38 MAPK can activate, in response to cellular stress, ATF-2 by phosphorylating this protein at Thr69 and Thr71. Mutations of these sites result in the loss of stress-induced transcription by ATF-2 (2-4).

Cross reactivity determined by western blot only.

Products Data 

 

A. Western blot analysis on HeLa cell lysate using anti-Phospho-ATF-2 (pT71) RabMAb (cat. #1268-1); dilution 1:10,000. Cells were (1) untreated, and (2) treated with Anisomycin.
B. Immunofluorescent staining of HeLa cells using anti-Phospho-ATF-2 (pT71) RabMAb (cat. #1268-1).

Specificity
A synthetic phospho-peptide corresponding to residues surrounding Thr71 of human ATF-2 was used as immunogen. The antibody only detects ATF-2 phosphorylated on Threonine 71

Storage Condition and Buffer
Store at -20 °C. Buffer: 50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA. Stable for 12 months from date of receipt.

Alternative Names
ATF2 antibody, CRE-BP1 antibody, CREB2 antibody, HB16 antibody, MGC111558 antibody, TREB7 antibody, Cyclic AMP-dependent transcription factor ATF-2 antibody, HB16 antibody, cAMP response element-binding protein CRE-BP1 antibody
