RNA-binding protein condensate maturation from reversible phase separation to amyloid-like aggregation should produce a measurable proximal phenotype before late disease pathology. The decisive test is time-resolved iPSC motor-neuron perturbations combining RNA stoichiometry, PTM mapping, live-cell condensate tracking, and cryo-electron tomography.
Symmetric dimethylation of arginine residues in the FUS RGG1/RGG2 domains by PRMT5/PRMT1 maintains FUS in a dynamic liquid phase-separated state by reducing inter-molecular beta-sheet propensity. ALS-linked mutations near the RGG domains reduce arginine methylation efficiency, shifting FUS toward an aggregation-prone unmethylated state. PRMT5 activator treatment in FUS-ALS iPSC motor neurons should restore arginine methylation stoichiometry and increase the concentration required for pathologica
