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
## Mechanistic Overview
ASO-Mediated Exon Skipping to Restore FUS-TAZ Chaperone Axis starts from the claim that modulating FUS within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "# ASO-Mediated Exon Skipping to Restore FUS-TAZ Chaperone Axis ## Background and Rationale Fused in Sarcoma (FUS) is a multifunctional DNA/RNA-binding protein belonging to the FET family that plays critical roles in transcription regulation, RNA proce
