Subcellular membrane-less assemblies are a reinvigorated area study in biology with spirited scientific discussions on the forces between the low-complexity protein domains within these assemblies. To illuminate these forces we determined atomic structures of five segments of protein low-complexity domains associated with membrane-less assemblies. Their common structural feature is the stacking of segments into kinked β-sheets which pair into protofilaments. Unlike steric zippers of amyloid fibrils, the kinked sheets interact weakly through polar atoms and aromatic sidechains. By computationally threading the human proteome on our kinked structures, we identified hundreds of low-complexity segments potentially capable of forming such interactions. These segments are found in proteins as diverse as RNA binders, nuclear pore proteins, and keratins, known to form networks and localize to membrane-less assemblies. Threading reveals hundreds of low-complexity segments in the human proteome capable of forming kinked multivalent protofilaments.
