ALS-linked FUS mutations (P525L, R521C) impair nuclear import via karyopherin-β2 (Transportin-1), causing cytoplasmic accumulation and splicing dysregulation. A compound screen for nuclear import correctors is proposed. Critical weaknesses include lack of validated small-molecule PPI modulators for FUS-Transportin-1, insufficient correlation between N/C ratio and functional splicing restoration, and stress granule pathology that may persist even with partial nuclear import restoration.
## 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
