The structural basis of cargo transport by the dynein/dynactin transport machine.
Group Leader page
The health of a neuron depends on long range transport. My group is interested in dynein, a microtubule motor protein that moves survival factors, protein-aggregates, viruses and many other cargos back along the axon to the neuronal cell body.
Recently electron cryo-microscopy revealed how dynein and its cofactor dynactin come together to form a multi-protein transport machine. The current challenge is to understand how this core complex selects its cargos.
This PhD position will form part of our effort to tackle this problem. It will use structural approaches (electron cryo-microscopy / electron cryo-tomography) on purified cargos together with correlative light and electron microscopy (CLEM) to visualize transport complexes directly within neurons.
