Abstract:
Viruses are powerful tools to uncover cellular processes. Through viral studies we have recently identified a novel translational control mechanism that involves the DEAD-box helicase Dhh1/DDX6 and RNA folding within coding sequences (CDSs). All Dhh1-dependent mRNAs, viral and cellular ones, (i) contain long and highly structured CDSs, (ii) are directly bound by Dhh1 with a specific pattern, (iii) are activated at the translation initiation step and (iv) express proteins associated with the endoplasmic reticulum. The obtained results uncover a novel layer of translation regulation associated with translation at the endoplasmic reticulum conserved from yeast to humans and hijacked by viruses.
