Encapsidation and expression of the herpes thymidine kinase gene in polyoma virus. 1982

N B Dinces, and G Milman

A recombinant DNA of 5,150 base pairs was prepared containing the intact early region of polyoma virus, including the viral origin of replication and the structural sequences of the herpes simplex virus type 1 thymidine kinase gene. Although no thymidine kinase activity was detected when herpes structural sequences alone were transfected into cells, activity was produced when the structural gene followed the polyoma early region. The recombinant DNA was encapsidated into polyoma virions when cotransfected into mouse 3T6 cells with helper DNA from an early polyoma virus mutant. Herpes thymidine kinase activity was detected by a rapid in situ autoradiographic assay in which [125]iododeoxycytidine was utilized as a substrate for the viral but not the cellular enzyme.
