MeSH definition : The prototypical and most well-studied member of the semaphorin family. Semaphorin-3A
is an axon-repulsive guidance cue for migrating neurons in the developing nervous
system. It has so far been found only in vertebrates, and binds to NEUROPILIN-1/plexin
complex receptors on growth cones. Like other class 3 semaphorins, it is a secreted
protein.;
