Proteolipid protein (PLP) is the major myelin protein of the CNS and is believed to have a structural role in maintaining the intraperiod line of compact myelin. An isoform. DM‐20. produced by alternative splicing of exon 3B is expressed earlier than PLP in the CNS and may be involved in glial cell development.

Proteolipids in developing rat brain
Neurochemical Research, 1985In this report data are summarized on changes in the quantity of proteolipid protein (PLP), its amino acid composition, and the lipid moiety of these lipid-protein complexes in rat brain during postnatal development. In all three parts of the central nervous system (CNS) studied (cerebral hemispheres, medulla oblongata and spinal cord) the main pattern

The term proteolipid was introduced by Folch and Lees (1951) to refer to a class of lipoproteins which are soluble in chloroform-methanol mixtures and insoluble in water. Lipoproteins are composed of a lipid moiety and a protein moiety, but the solubility properties of the proteolipids are the reverse of those of the serum lipoproteins.

Abstract: In a developmental study, we have shown that DM‐20 is present before proteolipid protein (PLP) in the fetal bovine cerebral hemispheres. When the white matter appears (27–30 weeks of gestation), the amount of DM‐20 drastically increases. DM‐20 remains the major proteolipid until birth.

Magnesium Inhibition of Apatite Nucleation by Proteolipid
Journal of Dental Research, 1981The effect of magnesium on apatite nucleation by Bacterionema matruchotii proteolipid was determined. The ion, in metastable calcium phosphate solution at a concentration that did not reduce proteolipid calcium binding, prevented apatite crystallization.

Proteolipid and Calculus Matrix Calcification In Vitro
Journal of Dental Research, 1977The initiator of calculus matrix calcification, in vitro, was isolated. Crude phospholipid, known to contain the factor, was separated into five fractions by column chromatography. A single protein-containing fraction induced apatite formation during incubation in a metastable calcium phosphate solution.

The Delipidation of Brain Proteolipid Protein by Ultrafiltration
Journal of Neurochemistry, 1983Abstract: It has been very difficult to prepare the apo‐protein moiety of brain white matter proteolipid so that it is completely devoid of complex lipids, without suffering aggregation and protein denaturation. The reason is that complex lipids are tightly bound to the proteolipid apo‐protein.

A convenient procedure is proposed for extracting mitochondrial proteolipids using a single phase mixture chloroform-methanol-water (1:2:0.8 v/v) with subsequent separation of the phases. The proteolipids were concentrated at the interface between the phases and thus purified from the bulk of the phospholipids.
