The promoter of the DDIT3 (CHOP) gene contains an Amino Acid Response Element (AARE) that binds ATF4 and ATF2. ATF2 and ATF4 are required for full activation of gene transcription in response to amino acid deprivation (Bruhat et al. 2000, Averous et al. 2004). Phospho-ATF2 is essential in the acetylation of histone H4 and H2B (Bruhat et al. 2007). ATF4 recruits PCAF to enhance transcription (Chérasse et al. 2007). ATF4 appears to be a monomer in the absence of DNA and a dimer after binding DNA (Podust et al. 2001).
