ATF4 binds a composite CEBP-ATF element in the promoter of the DDIT3 (CHOP, GADD153) gene in response to oxidative stress caused by arsenite (inferred from rat homologs) and amino acid deficiency (Bruhat et al. 2000, Averous et al. 2004, Bruhat et al. 2007, Cherasse et al. 2007). Both arsenite and heme deficiency regulate DDIT3 via EIF2AK1 (HRI) therefore heme deficiency is inferred to produce similar regulation of DDIT3 by ATF4. (Amino acid deficiency regulates DDIT3 via EIF2AK4.) The CEBP binding partner of ATF4 at the CEBP-ATF4 site is unknown. Phosphorylated ATF2 together with ATF4 activate DDIT3 in response to amino acid deficiency (Bruhat et al. 2000, Averous et al. 2004, Bruhat et al. 2007), however the role of ATF2 in heme deficiency is unknown.
