Proteins such as FUS phase separate to form liquid-like condensates that can harden into less dynamic structures. However, how these properties emerge from the collective interactions of many amino acids remains largely unknown. Here, we use extensive mutagenesis to identify a sequence-encoded molecular grammar underlying the driving forces for phase separation of proteins of the FUS family, and test aspects of this grammar in cells. Phase separation is governed primarily by multivalent interactions amongst tyrosine residues from prion-like domains and arginine residues from RNA binding domains, which are modulated by negatively charged residues. Glycine residues enhance the fluidity, whereas glutamine and serine residues promote hardening. We develop a model to show that the measured saturation concentrations of phase separation are inversely proportional to the product of the numbers of arginine and tyrosine residues. These results suggest it is possible to predict phase separation properties based on amino acid sequence. The phase separation behavior of FUS family proteins can be predicted from the prevalence and position of specific amino acids.
