ATF2 (pThr51/pThr69) antibody
Rabbit anti ATF2 (pThr51/pThr69) antibody recognizes activating transcription factor 2 (ATF2), also known as cyclic AMP-dependent transcription factor ATF-2 and cyclic AMP-responsive element-binding protein 2 (CREB-2), when phosphorylated at threonine 51 or threonine 69. ATF2 is a member of the ATF family of transcription factors containing single bZIP and C2H2-type zinc finger domains. ATF2 plays a role in the regulation of genes involved in cell differentiation, growth and the response to stress and DNA damage.
ATF2 binds to the cAMP responsive element (CRE), stimulating CRE- dependent transcription (Shuman et al. 1997). ATF2 also functions as a histone acetyltransferase (HAT), specifically acetylating histones 2B and 4 in vitro (Kawasaki et al. 2000).
ATF2 is phosphorylated at threonine 69 and threonine 71 by JNK1, JNK2 and p38 MAPK, enhancing the transcriptional activity of ATF2 (Yamasaki et al. 2009).
