Summary: A structural constituent of myelin sheath. Involved in several processes, including AMPA selective glutamate receptor signaling pathway; nervous system development; and positive regulation of calcium ion transmembrane transport. Located in myelin sheath. Part of integrin alphav-beta3 complex. Used to study demyelinating disease and visual epilepsy. Human ortholog(s) of this gene implicated in Pelizaeus-Merzbacher disease and hereditary spastic paraplegia 2. Orthologous to human PLP1 (proteolipid protein 1).

All pups with exposure to methadone demonstrated decreased expression of PLP in the cerebral cortex and hippocampus.In the cerebellum, PLP expression was downregulated without apparent alteration of CNP and MBP expression. PLP and MBP expression, but not CNP expression, were significantly inhibited in the brainstem.

PLP and DM-20 mRNA expression is restricted to oligodendrocyte-lineage cells
Title: The expression of PLP/DM-20 mRNA is restricted to the oligodendrocyte-lineage cells in the adult rat spinal cord.
Protein levels of PLP were significantly greater in orbital frontal cortex (OFC) but not dorsal striatum (dSTR) of females as compared to males, suggesting that myelination is increased in OFC but similar in dSTR of females as compared to males

Perinatal methylmercury exposure reduces the expression of Plp1 and Cnp splice variants in cerebellum of rat pups.

PLP localization in the cell membrane is altered in myelination-inhibiting fibronectin substrates.
Title: The lateral membrane organization and dynamics of myelin proteins PLP and MBP are dictated by distinct galactolipids and the extracellular matrix.
PLP transport to the myelin membrane proceeds via a transcytotic mechanism mediated by sulfatide with a conformational alteration and transient partitioning of PLP into distinct membrane microdomains involved in biosynthetic and transcytotic transport

We conclude that an ESE in exon3B regulates PLP 5' donor site selection and that ASF/SF2 protein participates in the regulation of PLP alternative splicing in oligodendrocytes.

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.
