    摘要: A yeast homologue of mammalian DNA ligase IV is provided and a role for DNA ligase IV established in the Ku-associated DNA repair pathway. Additionally interactions between DNA ligase IV and XRCC4, and interaction between XRCC4 and DNA-PKcs/Ku are established, providing for assays for agents which modulate such interactions and therefore cellular DNA repair activity. Such agents are useful in treatment of cancers, retroviral infections, immune system disorders and other conditions in which cellular DNA repair activity plays a role. Individuals with a predisposition to a disorder in which DNA repair plays a role may be diagnosed, by screening for the presence or absence of a defect in XRCC4 and/or DNA ligase IV activity.

    摘要: Ku(Ku70 and Ku80) of yeast and mammalian cells and other components of the Ku-associated DNA repair pathway are involved in retrotransposon and retroviral integration into cellular nucleic acids. Agents which inhibit activity of the pathway are useful for inhibition of retroviruses. Such agents are obtainable using assays involving the Ku-associated DNA repair pathway and one or more components thereof.
