Enzymic methylation of myelin basic protein in myelin.
Myelin fractions with different degrees of compaction were isolated from bovine brain, and post-translational methylation of membrane-associated proteins was studied. When the purified myelin-basic-protein-specific protein methylase I and S-adenosyl-L-[methyl-14C]methionine were added exogenously, the most compact myelin fraction exhibited higher methyl-accepting activity than the less compact ...
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...
متن کاملStudies on myelin-basic-protein methylation during mouse brain development.
The synthesis and methylation in vivo of myelin basic protein (MBP) during the mouse brain development has been investigated. When mice ranging in age from 13 to 60 days were injected intracerebrally with L-[methyl-3H]methionine, the incorporation of radioactivity into MBP isolated from youngest brain was found to be the highest and declined progressively in mature brains. This pattern of radio...
متن کاملPhosphorylation of myelin basic protein.
Myelin membranes prepared from rat brain possess both the enzyme and substrates to incorporate azP from (ya2P]ATP into membrane protein constituents. Qf the myelin polypeptides, only the two basic proteins were phosphorylated ; and both components appeared to be equally good substrates for endogenous or added protein kinases. The a2P was transferred primarily to serine residues of the basic pro...
