Abstract:
:At least three separate regions of the Epstein-Barr virus (EBV) genome encode RNA in a cell line that is growth transformed and nonpermissively infected with EBV. Six polyadenylylated cytoplasmic RNAs have been identified from these three regions. An abundant RNA 3.0-3.1 kilobases (kb) long is encoded by DNA of the internal reiteration, IR, and DNA that maps at 25.7-30 megadaltons. A second, abundant, 2.9-kb RNA is primarily encoded by DNA at 110-03 megadaltons but probably has a 3' end to the left of 110 megadaltons. A third, abundant, 3.7-kb RNA is largely encoded by DNA at 63-66 megadaltons and has a 5' end to the left of 63 megadaltons. A less-abundant 1.5-kb RNA is also encoded by IR. The least-abundant polyadenylylated RNAs identified are 2.3 and 2.0 kb. These RNAs have 3' ends mapping of 5-7 megadaltons and 5' ends mapping to the right of 7 megadaltons. The data suggest that there may be two additional polyadenylylated cytoplasmic RNAs, a 3-kb RNA mapping at 26.2-30 megadaltons and a minor RNA mapping at 102-110 megadaltons. An abundant 0.16-kb nonpolyadenylylated RNA is also present in the cytoplasm of IB-4 cells. This RNA precipitates from the cytoplasm in the presence of high concentrations of magnesium, indicating that it is complexed with protein or polyribosomes.
