Cytokeratin intermediate filaments
WebCytokeratins (CKs) are intermediate filaments. Together with microfilaments and microtubules, IFs form cytoskeleton of all eukaryotic cells. They are polypeptide filaments radiating from the nucleus and extending to the plasma membrane. Based on their composition, they are divided into five types (From Class I through Class V) (1) (2). WebMonoclonal antibodies to rat liver intermediate filament cytokeratins (CK49 and CK55) each stained intermediate filaments located in the cell cortex, within the cytoplasm and …

There are about 70 different human genes coding for various intermediate filament proteins. However, different kinds of IFs share basic characteristics: In general, they are all polymers that measure between 9–11 nm in diameter when fully assembled. Animal IFs are subcategorized into six types based on similarities in amino aci… WebDec 1, 2024 · Keratin filaments are always heteropolymers composed of an equal number of subunits from each subfamily of keratin.

Cytokeratins range in molecular weight between 40 kDa- 68 kDa, and an isoelectric pH between 4.9-7.8.
WebNeurofilament light polypeptide, also known as neurofilament light chain, abbreviated to NF-L or Nfl and with the HGNC name NEFL is a member of the intermediate filament protein family. This protein family consists of over 50 human proteins divided into 5 major classes, the Class I and II keratins, Class III vimentin, GFAP, desmin and the others, the … WebMallory bodies (Mallory hyaline) are irregular, ropelike eosinophilic intracytoplasmic strings that represent aggregates of cytokeratin intermediate filaments (cytokeratins 8 and 18). The cytokeratins form a filamentous support network within the hepatocytes.
