Myelin Membrane Assembly Is Driven by a Phase Transition of Myelin Basic Proteins Into a Cohesive Protein Meshwork
Rapid conduction of nerve impulses requires coating of axons by myelin. To function as an electrical insulator, myelin is generated as a tightly packed, lipid-rich multilayered membrane sheath. Knowledge about the mechanisms that govern myelin membrane biogenesis is required to understand myelin disassembly as it occurs in diseases such as multiple sclerosis. Here, we show that myelin basic pro...
متن کاملDevelopmental partitioning of myelin basic protein into membrane microdomains.
Specific membrane microdomains (including lipid rafts) exist in myelin but have not been fully characterized. Myelin basic protein (MBP) maintains the compactness of the myelin sheath and is highly posttranslationally modified. Thus, it has been suggested that MBP might also have other functions, e.g., in signal transduction. Here, the distribution of MBP and its modified forms was studied, spa...
متن کاملMyelin basic protein is affected by reduced synthesis of myelin proteolipid protein in the jimpy mouse.
Myelin basic proteins (MBPs) from 6-day-old, 10-day-old, 20-day-old and adult normal mouse brain were compared with those from 20-day-old jimpy (dysmyelinating mutant) mouse brain to determine the effect of reduced levels of proteolipid protein (PLP) on MBPs. Alkaline-urea-gel electrophoresis showed that 6-day-old and 10-day-old normal and jimpy MBPs lacked charge microheterogeneity, since C8 (...
متن کاملMyelin basic protein.
The fact that central nerve tissue is encephalitogenic has been known since the observation of a post-injection reaction of some rabies victims to the Pasteur vaccine that contained nerve tissue (Brostoff, 1977). Subsequently the encephalitogenic agent in central nerve tissue was traced to a component of the myelin sheath, and a protein was finally isolated that in the presence of complete Freu...
متن کاملSerum and Saliva Myelin Basic Protein as Multiple Sclerosis Biomarker
Objective: Multiple sclerosis (MS) is presented with motor and sensory function loss. It is caused by demyelination and following axonal lesion. As myelin basic protein (MBP) is one of the key elements of the myelin cover, we examined the level of MBP in serum, stimulated, and unstimulated saliva as a suitable biomarker for detecting MS. Methods: A case-control study was performed in 29 health...
