title: Thymidine kinase of rat liver. Activation by phospholipase C and subcellular distribution in the liver.
abstract: 1. The thymidine kinase activity of rat liver is greatly enhanced on addition of phospholipase C to the assay mixture. 2. Most of the thymidine kinase activity of the liver is recovered in the mitochondrial and in the impure ;nuclear' fractions. No activity was detected in purified nuclei prepared in high-density sucrose. 3. A substantial thymidine kinase activity could be detected, with the aid of phospholipase C, in all rat tissues examined.
