||Recombinant human ATF2 (1-254) was expressed inE. colicells using a N-terminal GST tag. MW=55kDa.
||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. ATF2 is a target of the JNK signal transduction pathway. 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.
||Kinase Assay, Western Blot.
|Storage And Stability:
||Store product at –70°C. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
