Gene: PLXNB3 (plexin B3) Homo sapiens
Symbol: PLXNB3
Name: plexin B3
Description: The protein encoded by this gene is a member of the plexin family. It functions as a receptor for semaphorin 5A, and plays a role in axon guidance, invasive growth and cell migration. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2009]
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: FLJ76953; PLEXB3; plexin 6; plexin-B3; PLEXR; PLXN6
