Optineurin is a multi-functional autophagy receptor that plays important roles in selective autophagy, NF-κB signaling, and mitochondrial quality control. Mutations in the OPTN gene are associated with glaucoma and amyotrophic lateral sclerosis (ALS). In neurodegeneration, optineurin is involved in removing damaged mitochondria through mitophagy and in regulating neuroinflammatory responses.
Optineurin is a 577 amino acid protein containing multiple domains:
Optineurin is a multifunctional protein involved in:
| Disease | Role of Optineurin |
|---|---|
| ALS/FTD | OPTN mutations cause ALS/FTD; optineurin inclusions in motor neurons |
| Parkinson's Disease | Impaired mitophagy; optineurin in Lewy bodies |
| Glaucoma | OPTN mutations associated with primary open-angle glaucoma |
| Approach | Status | Description |
|---|---|---|
| Gene therapy | Preclinical | AAV-OPTN for ALS |
| Autophagy modulators | Preclinical | Enhance mitophagy |
| NF-κB inhibitors | Preclinical | Modulate neuroinflammation |
