Stowers researcher publishes DNA double-strand break repair discovery in Science
...ecomes phosphorylated by a DNA damage- recognizing factor
in the proximity of DNA double-strand breaks. This finding raised the possibility that the complex, which was called the dTip60 complex, might specifically be attracted by phospho-H2A.X/v, and thus targeted to sites of DNA damage. Dr. Kusch was...
