**Molecular Mechanism and Rationale**
The OPTN/TBK1 phosphorylation cascade represents a critical quality control mechanism for stress granule homeostasis, with mutations in either component leading to selective accumulation of pathological stress granules that drive motor neuron degeneration in amyotrophic lateral sclerosis (ALS). The molecular foundation of this hypothesis centers on the differential recognition and clearance of physiological versus pathological stress granules through distin
## **Molecular Mechanism and Rationale**
The hexanucleotide repeat expansion (GGGGCC) in the C9orf72 gene represents the most prevalent genetic cause of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), accounting for approximately 40% of familial ALS cases and 25% of familial FTD cases. This expansion undergoes repeat-associated non-ATG (RAN) translation, generating five distinct dipeptide repeat proteins (DPRs): poly-glycine-proline (poly-GP), poly-glycine-arginine (poly-
