Many proteins work like Swiss Army knives, fitting multiple functions into their elaborately folded structures. A bit mysteriously, some proteins manage to multitask even with structures that are unfolded and floppy—"intrinsically disordered." In this week's issue of Nature, scientists at The Scripps Research Institute (TSRI) report their discovery of an important trick that a well-known intrinsically disordered protein (IDP) uses to expand and control its functionality.
