Activating Transcription Factor 2
The His-tag recombinant protein is purified by affinity chromatography in combination with FPLC columns. The purified ATF2 is greater than 90% homogeneous based on SDS-PAGE analysis.
1 unit equals 1 nanogram of purified protein.
Recombinant ATF2 (1-505) can be used for in vitro phosphorylation, dephosphorylation assays and inhibitor screening assay. For Research Purposes Only.
The protein is in 20mM Tris-HCl pH7.9,100mM NaCl, 0.2mM EDTA, 1mM DTT and 20% glycerol. Stored at -70°C before use. Avoid repeated freeze thaw cycles.

The activating transcription factor 2 (ATF2), also known as CRE-BP1 (cAMP-responsive element binding protein 1), is a member of the leucine zipper family of DNA binding proteins and binds to both AP-1 and CRE DNA response elements of many viral and cellular promoters (1). ATF2 can be activated by a diverse number of cellular stresses such as inflammatory cytokines, genotoxic agents and UV irradiation through MAPK pathway (2-4). It is activated through phosphorylation at two phosphosites of Thr69 and Thr71 by upstream activators like JNK/p38 (MAPK14, SAPK2A) (2-4).
