Genetic analysis of Gv1, a gene controlling transcription of endogenous murine polytropic proviruses.
نویسندگان
چکیده
Gv1 is a genetic locus that coordinately regulates the expression of multiple murine leukemia virus-related endogenous proviral sequences. A quantitative nuclease protection assay for typing Gv1 inheritance has been developed. Use of this assay demonstrates that Gv1 controls transcription of polytropic but not of modified polytropic endogenous proviruses. A combination of genetic techniques were used to map Gv1; these analyses demonstrate that Gv1 lies approximately 37 centimorgans from the centromeric end of mouse chromosome 13.

Antigenic subclasses of polytropic murine leukemia virus (MLV) isolates reflect three distinct groups of endogenous polytropic MLV-related sequences in NFS/N mice.
Polytropic murine leukemia viruses (MLVs) are generated by recombination of ecotropic MLVs with members of a family of endogenous proviruses in mice. Previous studies have indicated that polytropic MLV isolates comprise two mutually exclusive antigenic subclasses, each of which is reactive with one of two monoclonal antibodies termed MAb 516 and Hy 7. A major determinant of the epitopes disting...

Polytropic murine leukemia viruses (MuLVs) are generated by recombination of ecotropic MuLVs with env genes of a family of endogenous proviruses in mice, resulting in viruses with an expanded host range and greater virulence. Inbred mouse strains contain numerous endogenous proviruses that are potential donors of the env gene sequences of polytropic MuLVs; however, the precise identification of...

Forty-seven endogenous polytropic murine viruses (Pmv) were identified by examination of proviral-cellular DNA junction fragment segregation in recombinant inbred (RI) mice. Most Pmv loci were found in more than one of the seven RI progenitor strains analyzed, but only four were present in all strains. Chromosomal assignments for 41 Pmv loci were determined by comparing their RI strain distribu...
متن کاملRole of APOBEC3 in Genetic Diversity among Endogenous Murine Leukemia Viruses
The ability of human and murine APOBECs (specifically, APOBEC3) to inhibit infecting retroviruses and retrotransposition of some mobile elements is becoming established. Less clear is the effect that they have had on the establishment of the endogenous proviruses resident in the human and mouse genomes. We used the mouse genome sequence to study diversity and genetic traits of nonecotropic muri...

To develop a better understanding of the interaction between retroviruses and their hosts, we have investigated the polymorphism in endogenous murine leukemia proviruses (MLVs). We used genomic libraries of wild mouse DNAs and PCR to analyze genetic variation in the proviruses found in wild mouse species, including Mus musculus (M. m. castaneus, M. m. musculus, M. m. molossinus, and M. m. domes...
