Here
we identify a novel and highly conserved mechanism of translational control involving RNA structures within coding sequences and the DEAD-box helicase Dhh1. Using yeast genetics and
genome-wide ribosome profiling analyses we show that this mechanism, initially derived from studies
of the Brome Mosaic virus RNA genome, extends to yeast and human mRNAs highly enriched in
membrane and secreted proteins. All Dhh1-dependent mRNAs, viral and cellular, share key common
features. First, they contain long and highly structured CDSs, including a region located around 42 to
120 nucleotides after the translation initiation site, second, they are directly bound by Dhh1 with a
specific binding distribution and third, complementary experimental approaches suggest that they are
activated by Dhh1 at the translation initiation step. Our results show that ribosome translocation is not the only unwinding force of CDS and uncover a conserved layer of translational control that involve
RNA helicases and RNA folding within CDS providing novel opportunities for regulation of
membrane and secretome proteins. Overall design: Cells were grown in rich medium and sequencing was performed on ribosome-protected footprints and matched samples of randomly fragmented polyA-enriched RNA.
