It remains unclear how a complex of Kinesin-1 with CRMP-2 or other cargo receptors is selectively transported to a growing axon.

It remains unclear how a complex of Kinesin-1 with CRMP-2 or other cargo receptors is selectively transported to a growing axon. Remaining Questions Significant progress has been made toward understanding the intracellular events during neuronal polarization. However, more questions remain. For example, what extracellular cues govern neuronal polarity in situ?
