General Information
Term keratin filament ID (Ontology) GO:0045095 (Gene Ontology)
Definition A filament composed of acidic and basic keratins (types I and II), typically expressed in epithelial cells. The keratins are the most diverse classes of IF proteins, with a large number of keratin isoforms being expressed. Each type of epithelium always expresses a characteristic combination of type I and type II keratins.[ ISBN:0716731363 ]
