Summary: Enables semaphorin receptor activity. Involved in several processes, including maintenance of synapse structure; nervous system development; and semaphorin-plexin signaling pathway. Acts upstream of or within nervous system development; regulation of axon extension involved in axon guidance; and regulation of negative chemotaxis. Is active in cerebellar climbing fiber to Purkinje cell synapse. Is expressed in several structures, including alimentary system; nervous system; and sensory organ. Orthologous to human PLXNA4 (plexin A4). [provided by Alliance of Genome Resources, Dec 2024]

The same anatomical and physiological consequences occur in Ednra(+/-); Plxna4(+/-) double heterozygotes, genetically confirming functional interaction. Second-order axon guidance therefore multiplexes a smaller number of guidance cues in sequential fashion, allowing precise refinement of axon trajectories.
Title: Venous endothelin modulates responsiveness of cardiac sympathetic axons to arterial semaphorin.
We show that PTP-3, a LAR homolog in Caenorhabditis elegans, participates in Sema2A-regulated axon guidance. PTPdelta, a member of vertebrate LAR class PTPs, is involved in Sema3A-regulated cortical dendritic growth. In Sema3A signaling, PTPdelta activates Fyn and Src kinases by dephosphorylating their C-terminal Tyr residues.

These findings implicate Semaphorin-6A - Plexin-A2/Plexin-A4 interactions in dorsal lateral geniculate nucleus axon guidance and in the spatiotemporal organization of guidepost cell populations in the mammalian subpallium.

These findings suggest that by interacting with PlexA4, TrkA plays a crucial role in redirecting local Sema3A signaling to retrograde axonal transport, thereby regulating dendritic GluA2 localization and patterning.

Both CLU and PLXNA4 have been genetically associated with Alzheimer disease (AD) risk and our data thus provide a direct relationship between two AD risk genes. Our data suggest that increasing the levels of PLXNA4 or targeting CLU-PLXNA4 interactions may have therapeutic value in AD.

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.
