Research Interests:

Gene expression regulation, mRNA localization to cellular organelles

Short Synopsis:

My research interests are on the molecular mechanisms that coordinate the regulated expression of genes. We are focusing on two central steps of gene expression: mRNA translation and mRNA localization. Studies in recent years revealed that these two steps are highly regulated, and many proteins are involved in regulation. We characterize the activity of these proteins and screen for new ones. The characterization step is done in collaboration with the LSE imaging facility and involves detection of mRNA and fluorescent proteins by the LSE microscopy unit. We also collaborate with the Bioinformatics unit in order to define protein structures, mRNA recognition motifs and mRNA-protein interfaces.
