Arginine-rich Peptides Can Actively Mediate Liquid-liquid Phase Separation

Studying liquid-liquid phase separation (LLPS) of proteins provides key insights into the biogenesis of membraneless organelles and pathological protein aggregation in disease. We have established a protocol for inducing the phase separation of arginine-rich peptides, which allows for studying their molecular determinants and dynamics ( Boeynaems et al., 2017 ).
