SEMA3B Inhibits axonal extension by providing local signals to specify territories inaccessible for growing axons. Expressed abundantly but differentially in a variety of neural and nonneural tissues. Belongs to the semaphorin family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
