Researchers Determine Structure of DNA Repair Protein http://www.hhmi.org/news/goldbergj.html
In every cell, a group of proteins called caretakers keeps vigil for signs of DNA damage. If damage is encountered, the proteins act swiftly to repair DNA and preserve the integrity of the genome. HHMI researchers have produced the first images of a protein that detects and repairs broken strands of DNA. The images show that the Ku protein is constructed to cradle DNA while the DNA is repaired and rejoined with great precision. Research published in the August 9, 2001, issue of the journal Nature.
