Proteins can play either pernicious or positive roles in the dynamics of disease. Some proteins that anchor to cell membranes promote the development of HIV (human immunodeficiency virus), while some proteins thwart the growth of cancer, for example. Researchers using UT’s supercomputer, Kraken, have found that combining experimental neutron-scattering methods with molecular simulations can tell them a lot about the conformational changes in proteins and how they bind to cell membranes.
