This gene encodes a member of the plexin-A family of semaphorin co-receptors. Semaphorins are a large family of secreted or membrane-bound proteins that mediate repulsive effects on axon pathfinding during nervous system development. A subset of semaphorins are recognized by plexin-A/neuropilin transmembrane receptor complexes, triggering a cellular signal transduction cascade that leads to axon repulsion. This plexin-A family member is thought to transduce signals from semaphorin-3A and -3C. [provided by RefSeq, Jul 2008]
GeneCards Summary for PLXNA2 Gene
PLXNA2 (Plexin A2) is a Protein Coding gene. Diseases associated with PLXNA2 include disuse amblyopia and hidradenoma. Among its related pathways are Axon guidance and Neuroscience. GO annotations related to this gene include receptor activity and semaphorin receptor activity. An important paralog of this gene is PLXNB2.
UniProtKB/Swiss-Prot for PLXNA2 Gene
Coreceptor for SEMA3A and SEMA6A. Necessary for signaling by SEMA6A and class 3 semaphorins and subsequent remodeling of the cytoskeleton. Plays a role in axon guidance, invasive growth and cell migration. Class 3 semaphorins bind to a complex composed of a neuropilin and a plexin. The plexin modulates the affinity of the complex for specific semaphorins, and its cytoplasmic domain is required for the activation of down-stream signaling events in the cytoplasm (By similarity).
