Optineurin (OPTN), also known as FIP-2 or NEMO-related protein (NRP), is a cytoplasmic protein associated with diverse cellular functions including membrane trafficking, vesicle transport, and cell cycle control. OPTN has also been identified as an autophagy receptor important in elimination of damaged mitochondria through mitophagy, a selective macroautophagy process. Mutations in the Optn gene have been linked to a variety of disorders including amyotrophic lateral sclerosis, glaucoma, and Paget's disease of bone. In vitro cellular studies suggest that optineurin recognizes various protein aggregates via its C-terminal coiled-coiled domain in a ubiquitin-independent manner and facilitates autophagic clearance of protein aggregates. Immunohistochemical analyses demonstrate the localization of OPTN to pathological tau tangles in Alzheimer's disease tissues, and Lewy bodies and neurites in Parkinson's disease tissues, supporting its role in neurodegenerative diseases.Product Details
