This gene encodes a transmembrane proteolipid protein that is the predominant component of myelin. The encoded protein may play a role in the compaction, stabilization, and maintenance of myelin sheaths, as well as in oligodendrocyte development and axonal survival. Mutations in this gene cause Pelizaeus-Merzbacher disease and spastic paraplegia type 2. Alternatively splicing results in multiple transcript variants, including the DM20 splice variant.

A study in mice demonstrated that the PLP1 mRNA was downregulated in the corpus callosum-external capsule at 2 days post-traumatic brain injury [Kounelis-Wuillaume et al. DOI:10.1177/08977151251390528]. In human postmortem brain tissue, the PLP1 mRNA was significantly reduced in the orbitofrontal white matter of subjects with major depressive disorder, alcoholism, or their comorbidity and its levels were strongly positively correlated with levels of the microRNA miR-21 [Miguel-Hidalgo et al. DOI:10.1016/J.Pnpbp.2017.08.009]. In a separate mouse model of developmental lead exposure, single-cell RNA-sequencing identified PLP1 as a key marker for oligodendrocyte clusters, with perinatal exposure associated with an increased proportion of oligodendrocytes in the adult hippocampus [Bakulski et al. DOI:10.1093/toxsci/kfaa069].
