Cracking the code of a shapeshifting protein

A shapeshifting immune system protein called XCL1 evolved from a single-shape ancestor hundreds of millions of years ago. Now, researchers at the Medical College of Wisconsin (MCW) discovered the molecular basis for how this happened. In the process they uncovered principles that scientists can use to design purpose-built nanoscale transformers for use as biosensors, components of molecular machines, and even therapeutics. The findings were published today in Science. The primary and senior authors of the manuscript, respectively, are MCW researchers Acacia Dishman, MD-Ph.D. student, and Brian Volkman, Ph.D., professor of biochemistry.
