Eukaryotic cilia and flagella are specialized organelles that are highly conserved from protists to mammals. These organelles consist of the membrane-sheathed axoneme, which is an extension of the mother centriole, and at least 360 associated proteins. Cilia have attracted much attention in recent years because of their role in the transduction of extracellular signals and their association with an expanding number of human disorders. Such disorders include respiratory distress

These organelles consist of the membrane-sheathed axoneme, which is an extension of the mother centriole, and at least 360 associated proteins. Cilia have attracted much attention in recent years because of their role in the transduction of extracellular signals and their association with an expanding number of human disorders. Such disorders include respiratory distress syndrome, male sterility, polycystic kidney disease, retinal degeneration, and Bardet-Biedl syndrome.
Cilium assembly is initiated by the docking and fusion of the mother centriole to the apical membrane of the cell. Cilia are assembled and maintained through intraflagellar transport (IFT). This process is carried out by two distinct protein complexes, IFT complex A and B, which contain at least six and sixteen subunits, respectively. These complexes transport ciliary cargos within cilia and flagella by interactions with the microtubule-associated motor proteins kinesin-II and dynein.
Research summary - we are focusing on a number of aspects in ciliogenesis, including centriole/basal body duplication, vesicle targeting to the ciliary base, flagellar pocket biogenesis and intraflagellar transport.
Technically, we mainly use X-ray crystallography to determine the structures of these proteins and their complexes. Other biophysical techniques such as static/dynamic light scattering (SLS/DLS), differential scanning calorimetry, and analytical ultracentrifugation will as well be employed to study the architecture and assembly of the proteins and their complexes. Small proteins and domains are also studied by nuclear magnetic resonance (NMR) spectroscopy, whereas large assemblies are examined by electron microscopy (EM). Our structural studies will be complemented by site-directed mutagenesis, in vitro biochemical experiments, and in vivo assays (mostly with our collaborators) to test our mechanistic hypotheses. The available new structures will enhance our understanding of how these complexes function and provide hints as to how their malfunction leads to human diseases.
