SEMA3B

The protein encoded by this gene belongs to the class-3 semaphorin/collapsin family, whose members function in growth cone guidance during neuronal development. This family member inhibits axonal extension and has been shown to act as a tumor suppressor by inducing apoptosis. Alternative splicing of this gene results in multiple transcript variants.

Semaphorin 3B

Inhibits axonal extension by providing local signals to specify territories inaccessible for growing axons.
