Summary: Involved in several processes, including myelination in peripheral nervous system; regulation of RNA splicing; and transmission of nerve impulse. Located in cytosol; nuclear speck; and plasma membrane. Is expressed in sciatic nerve and trigeminal nerve.

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.
