Over the last years, two teams of researchers at The Scripps Research Institute have steadily built a model of how a powerful DNA repair complex works. Now, their latest discovery provides revolutionary insights into the way the molecular motor inside the complex functions – findings they say may have implications for treatment of disorders ranging from cancer to cystic fibrosis.

In a paper published in an Advance Online Edition of Nature Structural and Molecular Biology March 27, 2011, the scientists say that the complex’s motor molecule, known as Rad50, is a surprisingly flexible protein that can change shape and even rotate depending on the task at hand.

The finding solves the long-standing mystery  Continue reading
