Splicing of Friend Murine Leukemia Virus env-mRNA Enhances Its Ability to Form Polysomes
Friend murine leukemia virus (MLV) belongs to the gamma retroviruses of the Retroviridae family. The positive-sense RNA of its genome contains a 5' long terminal repeat (LTR), 5' leader sequence, gag, pol, env, and 3' LTR. Transcription from proviral DNA begins from the R region of the 5' LTR and ends at the polyadenylation signal located at the R region of the other end of the 3' LTR. There is...
متن کاملInhibition of murine leukemia virus envelope protein (env) processing by intracellular expression of the env N-terminal heptad repeat region.
A conserved structural motif in the envelope proteins of several viruses consists of an N-terminal, alpha-helical, trimerization domain and a C-terminal region that refolds during fusion to bind the N-helix trimer. Interaction between the N and C regions is believed to pull viral and target membranes together in a crucial step during membrane fusion. For several viruses with type I fusion prote...
متن کاملNucleotide sequence of the env-specific segment of NFS-Th-1 xenotropic murine leukemia virus.
The sequence of 863 contiguous nucleotides encompassing portions of the pol and env genes of NFS-Th-1 xenotropic proviral DNA was determined. This region of the xenotropic murine leukemia virus genome contains and env-specific segment that hybridizes exclusively to xenotropic and mink cell focus-forming but not to ecotropic proviral DNAs (C. E. Buckler et al., J. Virol. 41:228-236, 1982). The u...
متن کاملSynthesis of murine leukemia virus proteins differentiating Friend erythroleukemia cells.
In agreement with previous observations, the Friend 745 line of virus-induced erythroleukemia cells can be induced by dimethyl sulfoxide to synthesize hemoglobin and to increase simultaneously their content of morpho logically recognizable virus particles, especially in cytoplasmic vesicles. In apparent contrast to the electron microscopic results, the cellular content of the major murine leuke...
