OPTN (Optineurin): OPTN is a protein involved in crucial cellular processes, including membrane trafficking, autophagy, and NF-ÎşB signalling. Mutations in this gene are linked to glaucoma and amyotrophic lateral sclerosis (ALS). Its roles in autophagy and neuroinflammation make it a significant focus in research on neurodegenerative disorders and neuronal cell death.
