Anti-ATF2

Activating transcription factor (ATF)-2, also designated CRE-BP1, is a member of the ATF/cyclic AMP-responsive element binding protein family of transcription factors. ATF2 has two unique characteristics: it mediates the adenovirus E1A-induced trans-activation and forms a heterodimer with c-Jun (1). ATF2 is a target of the JNK signal transduction pathway (2). ATF2 is phosphorylated by JNK on two closely spaced threonine residues within the NH2-terminal activation domain. The replacement of these phosphorylation sites with alanine inhibited the transcriptional activity of ATF2. Furthermore, p38 MAPK can also phosphorylate ATF2.
