Involvement of collapsin response mediator proteins in the neurite extension induced by neurotrophins in dorsal root ganglion neurons.

The pattern of sensory neuron extensions and connections is established during embryonic development through complex and varied guidance cues that control motility of growth cones and neurite morphogenesis. Semaphorins and neurotrophins are molecules that act as such cues. Collapsin response mediator proteins (CRMPs) are thought to be part of the semaphorin signal transduction pathway implicated in semaphorin-induced growth cone collapse.
