DEFINITION

Dynein structure 2008

Cytoplasmic dynein could be key to understanding neurodegeneration 2008

BicD and Egl associate with cargo before transport8. Cargo recognition may require additional, as yet unidentified, accessory proteins. (b) The cargo complex is recruited to the dynein–dynactin complex, at least in part, through interactions between Egl and the dynein light chain (Dlc)3. Observations in mammalian cells suggest that additional interactions between BicD and the dynein–dynactin complexes may also occur in Drosophila2, 11. © Dynein mediates minus-end-directed microtubule movement of the cargo complex. It is unclear if additional factors involved in cargo recognition remain part of the complex during transport. (d) Cargo, BicD and Egl are released from dynein at or near microtubule minus ends, whereas the dynein–dynactin complex is recycled to microtubule plus ends by kinesin-mediated transport6, 8, 12, 13. MT, microtubule.
