title: Perspectives on the use of an endogenous gene target in studies of mutational specificity.
abstract: Mutational spectra have become increasingly important tools in generating a molecular level understanding of mutagenesis in mammalian cells. The work in this field has primarily involved the use of shuttle vector systems although some work has also been reported using endogenous cellular genes as mutational targets. In this communication we discuss the relative utility of these two approaches. We specifically focus on UV light-induced mutagenesis since this agent has been studied in both types of system. We conclude that shuttle vector and endogenous gene studies of mutagenesis are highly complementary, each possessing unique advantages.
