Translation of GCN4 mRNA is activated when yeast cells are grown under conditions of amino acid limitation. In this study, we established the conditions through which translation of the GCN4 mRNA could be activated in a homologous in vitro system. This activation paralleled the in vivo situation: it required the small open reading frames located in the 5' untranslated region of the GCN4 mRNA, and it was coupled with reduced rates of 43S preinitiation complex formation. Translational derepression in vitro was triggered by uncharged tRNA molecules, demonstrating that deacylated tRNAs are more proximal signals for translational activation of the GCN4 mRNA.
