The study shows that G3BP1 ubiquitination inhibits LLPS in vitro, but the molecular mechanism by which K63-linked ubiquitin chains prevent phase separation is not explained. Understanding this mechanism is crucial for developing targeted therapies for neurodegenerative diseases where pathological stress granules persist.
