Specification of the axon and dendrites is a critical step in the development of a neuron and requires the asymmetric organization of the cell. A possible link between the extrinsic and intrinsic pathways that drive axon specification has been made with the finding that Dishevelled acts downstream of Wnt5a to activate the PAR6–aPKC–PAR3 pathway.
