| abstractText | The integrated proviral genome of Abelson murine leukemia virus (A-MuLV) was cloned in lambda gtWES . lambda B bacteriophage after EcoRI endonuclease digestion and enrichment of proviral sequences by sequential RPC-5 column chromatography and agarose gel electrophoresis. Recombinant DNA clones containing a 7.8-kilobase-pair EcoRI insert were shown to have the entire integrated A-MuLV genome with both 5' and 3' ends flanked by mink cellular DNA sequences. This DNA fragment was shown to induce focus transformation upon transfection of NIH/3T3 mouse cells. Moreover, focus-forming virus could be rescued from transformed nonproducer cells upon superinfection with a type C helper virus. A polyprotein of molecular weight 120,000 (p120) containing murine leukemia virus gag gene determinants was invariably deteced by immunoprecipitation analysis of individual transformants induced by the 7.8-kilobase-pair DNA. Molecularly cloned integrated A-MuLV in its infectious form should be of use in elucidating the mechanisms involved in transformation by this virus. |
