Motors for fast axonal transport.
Authors:T A Schroer
Institution:Department of Biology, Johns Hopkins University, Baltimore, Maryland 21218.
Abstract:In neurons and other animal cells, membrane-bound vesicles course rapidly along cytoskeletal filaments to reach their destinations. Based on a variety of in vivo studies it is becoming clear that the microtubule-based motor, kinesin (and its relatives), drive vesicle movements in axons. Surprisingly, some axonal membranes have the capacity to move on both microtubules and actin filaments.
