title: Cell cycle regulated synthesis of stable mouse thymidine kinase mRNA is mediated by a sequence within the cDNA.
abstract: The cDNA for mouse thymidine kinase (TK) was isolated from a cDNA library in lambda-gt11 and sequenced. It was used as a probe to follow the time course of TK mRNA expression in growth stimulated mouse fibroblasts. Linked to the HSV-TK promoter the cDNA was able to transform LTK-cells to the TK+ phenotype. The transformed cells expressed the TK mRNA and enzyme activity in a growth dependent fashion suggesting that the regulatory element is localized on the cDNA.
