Research identifies a critical regulatory mechanism in which KRAS proteins form cytoplasmic condensates through a process called liquid-liquid phase separation (LLPS). This phenomenon is specifically driven by farnesylation, a hydrophobic modification at the C185 residue that enables KRAS to aggregate into membrane-less droplets. These condensates facilitate essential protein processing by cluster...
