Summary: Enables semaphorin receptor activity. Involved in nervous system development; positive regulation of cytoskeleton organization; and semaphorin-plexin signaling pathway. Acts upstream of or within several processes, including hippocampus development; negative regulation of axon extension involved in axon guidance; and neuron development. Predicted to be part of semaphorin receptor complex. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; peripheral nervous system; and sensory organ. Orthologous to human PLXNA3 (plexin A3).

PLXNA1 and PLXNA3 may have roles in inherited GnRH deficiency and cooperate to pattern the nasal axons that guide gonadotropin-releasing hormone neurons
Title: PLXNA1 and PLXNA3 cooperate to pattern the nasal axons that guide gonadotropin-releasing hormone neurons.
genetic findings demonstrate that Sema3a repellent signaling plays a role in the establishment of proper afferent projections in SAG neurons, and this signaling likely occurs through a receptor complex involving Npn1 and either plexinA1 or plexinA3
Title: Deletion of Sema3a or plexinA1/plexinA3 causes defects in sensory afferent projections of statoacoustic ganglion neurons.
the plexin A3 GAP domain adopts a closed conformation and cannot accommodate R-Ras/M-Ras in its substrate-binding site, providing a structural basis for the autoinhibited state of plexins
Title: Crystal structure of the plexin A3 intracellular region reveals an autoinhibited conformation through active site sequestration.
The combined loss of PLXNA3 and PLXNA4 impaired facial branchiomotor axon guidance more severely than loss of either plexin alone, suggesting that SEMA3A and SEMA3F signals, even though both essential, are partially redundant.
Title: Plexin A3 and plexin A4 convey semaphorin signals during facial nerve development.
the signaling of plexin-A3, plexin-A4, and Sema6A is at least partially required for dorsal turning of the corticospinal tract axons
Title: Dorsal turning of motor corticospinal axons at the pyramidal decussation requires plexin signaling.
These results indicate that the stereotyped pruning of the visual and motor CST axon collaterals is differentially regulated and that this specificity arises from the differential expression of plexin receptors in the cortex.
Title: Plexin signaling selectively regulates the stereotyped pruning of corticospinal axons from visual cortex.
plexin-A3 and plexin-A4 are expressed in newly-differentiated sympathetic neurons, but not their neural crest precursors. They function cooperatively to regulate the migration of sympathetic neurons and then differentially to guide the sympathetic axons.
Title: Plexin-A3 and plexin-A4 restrict the migration of sympathetic neurons but not their neural crest precursors.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
