Translation of avian myeloblastosis virus RNA in a cell-free lysate of Escherichia coli.
In a cell-free extract of E. coli, RNA from avian myeloblastosis virus directs the synthesis of a protein that is antigenically identical with the group-specific antigen 4, and other proteins, three of which correspond in molecular weight to group-specific antigens 1-3.
متن کاملStructure and specific sequences of avian erythroblastosis virus RNA: evidence for multiple classes of transforming genes among avian tumor viruses.
Two major RNA species were found in several clonal isolates of avian erythroblastosis virus (AEV) and avian erythroblastosis-associated helper virus (AEAV) complexes: one of 8.7 kilobases (kb), the other of 5.5 kb. The 5.5-kb species was identified as AEV RNA because (i) it was absent from non-transforming AEAV isolated from the same virus complex, (ii) it was present in complexes of AEV and di...
متن کاملCell-free translation of paramyxovirus messenger RNA.
Polypeptides corresponding in electrophoretic mobility to virion polypeptides 1, 3, and 5 were made in a reticulocyte cell-free system to which 18S RNA from Sendai virus-infected cells was added. Immune precipitation was used to select relevant polypeptides from endogenous products. The cell-free product corresponding to virion polypeptide 3 (the nucleocapsid structure unit) was the most abunda...
متن کاملImmune abnormalities in avian erythroblastosis virus-infected chickens.
Infection of animals with retroviruses frequently leads to immunosuppressed states. The immune status of chickens injected with the replication-defective avian erythroblastosis virus (AEV), with its naturally occurring subgroup B helper virus (avian erythroblastosis-associated virus; AEAV), was evaluated daily and compared to the immune status of age-matched uninfected control chickens. Spleen ...
متن کاملTranslation of murine leukemia virus RNA in cell-free systems from animal cells.
The virion RNA of Moloney murine leukemia virus (MuLV) has been translated in eukaryotic cell-free systems derived from mouse L- and human HeLa cells. In both systems at least three polypeptides, approximately 60,000, 70,000, and 180,000 in apparent molecular weight, were formed in response to the added 35S MuLV RNA. All three polypeptides were precipitable with antiserum to detergent-disrupted...
