NCIt definition : Encoded by Intermediate Filament Genes, diverse Intermediate Filament Proteins (including
keratin filaments, neurofilaments, desmin, and vimentin) form polymeric structural
cytoplasmic filaments, intermediate in diameter (8-10 nanometer) between actin microfilaments
and microtubules, that comprise part of the cytoskeleton of most eukaryotic cells.
