Research Abstract |
The brain consists of the remarkably fine neural circuits. This circuits are made of axons, and CRMP-2 previously had been identified as a key molecule in axon formation. I analyzed the functional meaning of CRMP-2 in axon formation, and obtained the following results : 1) CRMP-2 regulates anterograde TrkB transport in axon through the association with Slp1 and Rab27. 2) CRMP-2 binds directly to cytoplasmic dynein, a motor protein of retrograde transport, and negatively regulates its function. These results suggest that CRMP-2 play a role in axon formation through regulating the molecular transport in axon.
