The ATF/CREB family of DNA binding proteins consists of transcription factors whose activity is regulated by specific signaling pathways, including the stress/cytokine/radiation inducible pathways that function through SAPK1/JNK activation. Two threonine residues at positions 69 and 71 in the N-terminal region of ATF-2 are essential in mediating adenovirus E1A-inducible transcriptional activation. These residues are efficiently phosphorylated in vivo and are excellent substrates for SAPK1/JNK in vitro.

Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
