Axonal transport and the cytoskeleton.

Great advances in the field of axonal transport have been made in the past year, including the identification of new molecular motors associated with microtubules and actin. In addition, studies on the mechanisms of bidirectional fast axonal transport have clarified new aspects of this process, such as the isolation of a kinesin-binding protein, kinectin, and the finding that phosphorylation regulates kinesin's dissociation from membranous organelles. New approaches to studying slow transport of cytoskeletal proteins have provided further evidence that the axonal cytoskeleton in mammalian systems is largely stationary, although a dynamic exchange occurs between polymers and a small pool of moving subunits.
