Summary: Enables identical protein binding activity and semaphorin receptor activity. Involved in several processes, including chordate embryonic development; limb bud formation; and semaphorin-plexin signaling pathway. Acts upstream of or within cell surface receptor signaling pathway; centrosome localization; and cerebellar granule cell precursor tangential migration. Located in plasma membrane. Is expressed in several structures, including branchial arch; central nervous system; genitourinary system; heart; and peripheral nervous system. Orthologous to human PLXNA2 (plexin A2).

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.
