Ribosomes are the universally conserved macromolecular machines that decode the mRNA to make proteins. However, it remains unclear how these large ribonucleoprotein particles are assembled. Defects in the ribosome assembly process cause the ‘ribosomopathies’, a fascinating new group of human developmental disorders that perturb haematopoietic stem cell function and promote progression to bone marrow failure, myelodysplastic syndrome and acute leukaemia. Our research on the mechanisms of ribosome assembly centres around the ribosomopathies with Shwachman-Diamond syndrome currently a key focus for us.
The key questions that underpin our current research are: what are the mechanisms of eukaryotic ribosome assembly; how is this process regulated and monitored; what are the cellular consequences of defective ribosome biogenesis; how do defects in this process cause human disease? My laboratory uses a highly interdisciplinary approach that combines genetics, biochemistry and high-resolution structural studies, with a particular focus on single-particle cryo-electron microscopy.
