Photoaffinity labelling of central-nervous-system myelin
1. Endogenous cyclic AMP-stimulated phosphorylation of a 49700-Mr Wolfgram protein component in rabbit central nervous system was investigated by using photoaffinity labelling and 2',3'-cyclic nucleotide 3'-phosphodiesterase activity staining after electroblotting on to nitrocellulose paper. 2. Photoaffinity labelling with 8'azidoadenosine 3',5'-cyclic monophosphate showed a cyclic AMP-binding ...
متن کاملPartial characterization of the phosphotransferase system of human central-nervous-system myelin.
The phosphotransferase system of human central-nervous-system myelin was investigated. Evidence obtained indicated the presence of at least two different phosphotransferase systems (cyclic nucleotide-dependent and -independent) in myelin, which were found to be firmly associated with the membrane. The cyclic AMP-dependent kinase of myelin and white-matter cytosol preferentially phosphorylated c...
متن کاملEvolution of a neuroprotective function of central nervous system myelin
The central nervous system (CNS) of terrestrial vertebrates underwent a prominent molecular change when a tetraspan membrane protein, myelin proteolipid protein (PLP), replaced the type I integral membrane protein, P0, as the major protein of myelin. To investigate possible reasons for this molecular switch, we genetically engineered mice to express P0 instead of PLP in CNS myelin. In the absen...
متن کاملBiogenesis and significance of central nervous system myelin.
The central nervous system is composed of neurons and glia cells. Although neurons have long been considered the functionally important cells, an ever-expanding body of research has revealed many critical functions of neuroglia. Among these, the myelin sheath elaborated by oligodendrocytes acts as a dynamic partner to the axons it enwraps and can no longer be considered as an inert membrane. In...
متن کاملUDP-galactose:ceramide galactosyltransferase of rat central-nervous-system myelin.
The properties of ceramide galactosyltransferase associated with myelin and microsomal fractions of rat brain were studied. The enzyme from both the fractions had similar properties during development and synthesized the same molecular species of the product cerebroside. The results suggested that during myelination the turnover rate of enzyme protein is altered instead of regulatory modulation...
