The protein collapsin was purified from chick brain on the basis of its ability to inhibit sensory neuron growth cones, implicating this molecule in sensory axon guidance (Luo et al. [1993] Cell 75:217-227). To examine the relationship between collapsin and sensory axon growth, we examined the pattern of mRNA expression of collapsin's mammalian paralogue, Semaphorin III (Sema III), and compared it to dorsal root ganglion (DRG) axon pathways in the developing rat embryo. Centrally, DRG axons… CONTINUE READING
