Research Interests:

Protein synthesis, an essential cellular process, is divided into four stages: initiation, elongation, termination and ribosome recycling. The mechanisms of the last two stages, termination and recycling, have been described only recently as a consequence of advances that permitted all stages of translation to be reconstituted in vitro from individual translational components: 40S and 60S ribosomal subunits, aminoacyl-tRNA, mRNA and translation factors. However, despite the fact that all factors required for the translation cycle have been identified, and their principal roles have been determined, the molecular mechanisms of many fundamental steps in translation remain unknown. The possibility to reconstitute the entire eukaryotic translation cycle in vitro from individual components permits the analysis of basic and regulatory molecular mechanisms of individual steps, and our laboratory employs this approach in conjunction with a variety of biochemical and biophysical techniques to address poorly characterized aspects of translation in higher eukaryotes.
