Aberrant splicing of proteolipid protein mRNA in the dysmyelinating jimpy mutant mouse.
cDNA clones encoding proteolipid protein (PLP) were isolated from a mouse brain library and sequenced. We describe two transcripts arising from the PLP locus by alternative splicing: the major one encodes the 277-amino acid PLP protein and the minor one corresponds to the DM-20 protein, a PLP-like protein of 20,000 Mr that shares both amino and carboxyl regions with PLP. These two transcripts l...
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 کاملCell-free acylation of rat brain myelin proteolipid protein and DM-20.
Incubation of rat brain myelin with [3H]palmitic acid in the presence of ATP, CoA and MgCl2 or [14C]-palmitoyl-CoA in a cell-free system resulted in the selective labelling of 'PLP' [proteolipid protein; Folch & Lees (1951) J. Biol. Chem. 191, 807-817] and 'DM-20' [Agrawal, Burton, Fishman, Mitchell & Prensky (1972) J. Neurochem. 19, 2083-2089] which, after polyacrylamide-gel electrophoresis in...
متن کاملSplice site selection in the proteolipid protein (PLP) gene transcript and primary structure of the DM-20 protein of central nervous system myelin.
Proteolipid protein (PLP) is the major myelin membrane protein of the central nervous system. We have isolated a copy of an alternatively spliced PLP gene transcript from a mouse brain cDNA library that was screened for PLP-related sequences. The encoded 241-amino acid protein differs from PLP by an internal deletion of 35-amino acid residues (116-150) from the major hydrophilic domain. This PL...
متن کاملInduction of the myelin proteolipid protein (PLP) gene in C6 glioblastoma cells: functional analysis of the PLP promotor.
The terminal differentiation of postmitotic oligodendrocytes is marked by the induction of myelin-specific genes. In this report, we demonstrate that culture conditions that induce oligodendrocyte differentiation of glial progenitor cells also induce differentiation of C6 glioblastoma cells, as monitored by activated transcription of the gene encoding proteolipid protein (PLP), the major myelin...
