We combine simulation and experiment to understand protein conformational changes, their role in signaling, and opportunities they present for drug design. For example, the movie shows the opening of an unexpected binding pocket that we have demonstrated may be a valuable drug target for combating antibiotic resistance. We are also interested in understanding the roles such conformational changes play in signaling cascades, such as those responsible for vision.
