Presentation
In every living organism, the production of ribosomes, the protein factories of the cell, is central to gene expression and cell metabolism. Tackling the high complexity of ribosome synthesis in human cells has been made more urgent by the recent linkage of congenital diseases and cancer predisposition to ribosome production defects. Our group focuses on the mechanisms of ribosome synthesis in human cells under several angles: pre-ribosomal RNA processing, nuclear export of pre-ribosomal particles, structure of the pre-ribosomes. This mechanistic framework allows us to characterize the functional impact of mutations affecting ribosome biogenesis in rare diseases (ribosomopathies), especially Diamond-Blackfan anemia.
