ATF-2 (activating transcription factor 2) transcription factor is a member of the leucine-zipper family of proteins and was previously known as cAMP responsive element binding protein 2 (or CREB2). ATF 2 is a transcriptional activator that binds the cAMP-responsive element (CRE) and interacts with c-Jun to stimulate CRE transcription. This protein is also capable of acetylating Histone H2B and Histone H4 in vitro as a histone acetyltransferase (HAT).

Positive Control

Active Motif's HeLa nuclear extract (TNF-α stimulated) (Catalog No. 40210) can be used as a positive control for ATF-2 phospho Thr71 antibody.


Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.


This product is guaranteed for 6 months from date of receipt.
