Biological activities of deletion mutants of simian virus 40.
Mutants of Simian virus 40 (SV40) with large deletions in the early or late regions of the genome were tested for biological activity. Deletion mutants lacking portions of both late genes (B/C and D), but with an intact early genomic segment, were able to induce T antigen in infected cells, replicate their DNA in the absence of helper virus, stimulate thymidine incorporation into cellular DNA, ...
متن کاملProposal for a uniform nomenclature for simian virus 40 mutants.
A uniform nomenclature for simian virus 40 mutants has been developed. This nomenclature should evolve into a comprehensive nomenclature as new mutants and information are obtained. Hopefully, his nomenclature will also stimulate the development of a comprehensive nomenclature for all animal virus mutants.
متن کاملProteins in intracellular simian virus 40 nucleoportein complexes: comparison with simian virus 40 core proteins.
Intracellular nucleoprotein complexes containing SV40 supercoiled DNA were purified from cell lysates by chromatography on hydroxyapatite columns followed by velocity sedimentation through sucrose gradients. The major protein components from purified complexes were identified as histone-like proteins. When analyzed by electrophoresis in sodium dodecyl sulfate-polyacrylamide gels, complex protei...
متن کاملSuperinfection of simian virus 40-transformed permissive cells with simian virus 40.
Evidence that the resistance of simian virus (SV40)-transformed permissive cells to superinfection with SV40 is due to lack of virus uptake is presented. When virus uptake is enhanced, the events of infection proceed as in normal permissive cells, resulting in production of infectious virus.
متن کاملAssociation of simian virus 40 T antigen with simian virus 40 nucleoprotein complexes.
Viral nucleoprotein complexes were extracted from the nuclei of simian virus 40 (SV40)-infected TC7 cells by low-salt treatment in the absence of detergent, followed by sedimentation on neutral sucrose gradients. Two forms of SV40 nucleoprotein complexes, those containing SV40 replicative intermediate DNA and those containing SV40 (I) DNA, were separated from one another and were found to have ...
