Research Overview
The regulation of mRNA translation into protein is fundamental for life. Translation is controlled mainly during its initiation stage. Our lab uses cryo-electron microscopy in combination with biochemical and genetic approaches to study the role of a family of enzymes called DEAD-box (DDX) RNA helicases in the regulation of translation initiation, and how this initiation is regulated in health and disease.
