Intermediate Filament Gene

**Semantic type:** Gene or Genome

**Definition:** Intermediate Filament Genes encode a number of different Intermediate Filament Proteins (including keratin filaments, neurofilaments, desmin, and vimentin) that form polymeric structural cytoplasmic filaments, intermediate in diameter (8-10 nanometer) between actin microfilaments and microtubules, which comprise part of the cytoskeleton of most eukaryotic cells.
