66 kDa neurofilament protein,AINX,Alpha Inx,Alpha-internexin,Alpha-Inx,INA,Internexin neuronal intermediate filament protein alpha,MGC12702,NEF 5,NEF5,Neurofilament 5 (66kD),Neurofilament 5,Neurofilament 66,Neurofilament 66 tax binding protein,Neurofilament-66,NF 66,NF-66,NF66,TXBP 1,TXBP1,Neurofilaments are type IV intermediate filament heteropolymers composed of light, medium, and heavy chains. Neurofilaments comprise the axoskeleton and they functionally maintain the neuronal caliber. They may also play a role in intracellular transport to axons and dendrites. This gene is a member of the intermediate filament family and is involved in the morphogenesis of neurons.
