Mobilizing the repair squad: Critical protein helps mend damaged DNA
23 minutes ago ago from Xenophilia (True Strange Stuff)
In order to preserve our DNA, cells have developed an intricate system for monitoring and repairing DNA damage. Yet precisely how the initial damage signal is converted into a repair response remains unclear. Researchers at the Salk Institute for Biological Studies have now solved a crucial piece of the complex puzzle. In a forthcoming article in the Dec. 24 issue of Molecular Cell, they show that a protein named CtIP plays an essential ...
