Dynamic protein interfaces and conformational landscapes of membrane protein complexes

•Dynamic membrane protein interfaces, in particular in GPCRs suggest novel regulatory and organizational paradigms.•Long timescale atomistic simulations give a glimpse of interactions between disordered binding regions.•Coarse-grain simulations are able to capture multiple binding modes of protein-protein interfaces.•Integrative coarse-grain and atomistic simulations with enhanced sampling techniques are the way forward.
