0 a strong natural protein, which is the main substance that forms hair, nails, hooves, horns, feathers, etc.: --
We have studied the composition, shape, and behaviour of feather keratins.
Rhino horn is made of keratin, the same material as hair and fingernails.
A thick layer of keratin develops, to which the patient is usually oblivious, and autolysis takes place underneath.
These may not be inhibited by heavy metals, but are unable to initiate a proper cyst without the presence of the ' keratin-like ' granules.
Diversity of intermediate filament structure : evidence that the alignment of coiled-coil molecules in vimentin is different from that in keratin intermediate filaments.
Repeating patterns of amino acid residues in the sequences of some high-sulphur proteins from keratin.
Plakins serve two roles: they anchor the keratin intermediate filaments to the nuclear and plasma membranes, and they connect intermediate filaments, microtubules and microfilaments together.
The most common were actinrelated and keratin-associated proteins.
Similarly, in keratinocytes, keratin molecules containing one particular chain pair will ultimately be replaced by molecules comprising a different chain pair as differentiation proceeds.
So far no discussion has been made of the trichocyte keratins.
