|Our research is concerned with protein synthesis, protein folding and translational control of gene expression in eukaryotic cells. Research in the laboratory has 3 major foci:
1. We are interested in protein structure/function relationships and the rational protein design. Proteins are constructed in many cases from a number of structurally and/or functionally conserved modules that are genetically mobile and used repeatedly in the course of evolution. These modules may be sufficiently large so as to constitute an entire protein domain or as small as a short peptide composed of a few amino acids. We are in interested in the design of chimeric proteins with novel properties.
2. A large body of work in the laboratory is concerned with the mechanism of protein synthesis and translational control of gene expression in eukaryotic cells. Recent studies have pointed to the key role of translational control in regulating gene expression during development, differentiation, cell cycle progression, cell growth, apoptosis, and stress. Regulation of translation is mainly exerted at the initiation step of protein synthesis, thus allowing rapid modification of the overall rate of translation as well as post-transcriptional regulation of gene expression due to changes in the relative selection of different mRNA species utilizing different mechanisms of translation initiation. Assembly of the 80S ribosome at a start codon within the majority of eukaryotic mRNAs involves recruitment of the 40S ribosome (and associated initiation factors) to the mRNA 5'-end followed by ribosome scanning (in search of the initiation codon). However, it was shown that some mRNAs can be translated via internal initiation, a process that is generally independent of the recognition of the 5'-mRNA end and involves direct recruitment of the 40S ribosome to the vicinity of the initiation codon (directed by internal ribosome entry site (IRES) elements). We are interested in the mechanism of the initiation of protein synthesis, the IRESs function and factors that affect IRESs activity. We are in particular interested in the structure and function of certain ribosomal proteins that may affect initiation of protein synthesis.
3. The research in the laboratory is further devoted to the co-translational protein folding and the impact of synonymous mutations on gene function and phenotype. The journey of nascent polypeptides from synthesis at the peptidyl transferase center of the ribosome to full function involves multiple interactions, constraints, modifications and folding events. Each step of this journey impacts the ultimate expression level and functional capacity of the translated protein. It has become clear that the kinetics of protein translation is predominantly modulated by synonymous codon usage along the mRNA, and that this provides an active mechanism for coordinating the synthesis, maturation and folding of nascent polypeptides.
