Membraneless liquid compartments based on phase-separating biopolymers have been observed in diverse cell types and attributed to weak multivalent interactions predominantly based on intrinsically disordered domains. Here the authors design protein liquid condensates from tunable concatenated coiled-coil dimer modules, unraveling the principles for coexisting condensates, chemical regulation, formation from either one or two polypeptide components in mammalian cells.
