Proteins are the workhorses of life. Organisms use them as building blocks, receptors, processors, couriers and catalysts. A protein's structure is critical to its function. Malformed proteins not only fail to carry out their tasks, they can accumulate and eventually gum up the inner workings of cells. As a result, misfolded proteins cause a variety of degenerative diseases, from Alzheimer's and Parkinson's to the blinding disease retinitis pigmentosa. These disorders are currently incurable.
