The ATF5 mRNA is translated to yield ATF5 protein (Watatani et al. 2008, and inferred from the mouse homolog) which is then imported into the nucleus. The ATF5 mRNA contains 2 upstream ORFs (uORFs) which inhibit translation of the downstream ATF5 coding region (Watatani et al. 2008). Translation of uORF2 also targets the mRNA for nonsense-mediated decay (Hatano et al. 2013). During stresses such as amino acid limitation and arsenite-induced oxidative stress, EIF2S1 (eIF2-alpha) is phosphorylated, decreasing translation initiation at the uORFs and increasing translation of ATF5 (Watatani et al. 2008, and inferred from the mouse homolog).
