Science is receptive to new information that can refine the theories we use to make sense of the world. Such is the case with Dr. Lauren Porter, a Stadtman investigator at the National Library of Medicine who is helping redefine the way we understand how proteins behave. She is looking at a new class of proteins that can change their structure and function much like the famous Transformer robots that morph into different machines. Understanding how these proteins switch their shape could help scientists understand the molecular basis of certain diseases like cancer and Alzheimer’s.
