A protein of molecular size 180 kilodaltons is associated with 10-nanometer filaments in neurons and is immunologically distinct from smaller putative neurofilament subunits and from 10-nanometer filament proteins in nonneuronal cells, such as myotubes and fibroblasts. Neurons do not contain vimentin, the major filament protein in many other cells, including the nonneuronal cells in cultures of neural tissue.
