Description: Keratins are proteins found in skin, nails, horn, claws, and hair. They
offer a strong structure and protection for the cells. Keratin is an
intermediate filament, consisting of two parallel helices. They are known
to contain a lot of the amino acid glycine.
Description: Lamin is a cytoskeleton protein that provides structural support to the
inner lining of the nuclear envelope within cells. As an intermediate
filament it consists of two parallel helices.
Description: Neurofilaments are class III and IV intermediate filaments found
specifically in neurons. Class IV filaments are found in heteropolymers of
the three subunit types NF-L, NF-M, and NF-H. They were originally
designated based on their separation on SDS-PAGE
Description: Vimentins are cytoskeletal proteins involved in cellular structural support
offering flexibility to a cell. They are a class III intermediate filament
subunit in developing neurons. They are also found attached to the nucleus,
endoplasmic reticulum, and mitochondria positioning and anchoring them in
the cytoplasm.
