Ví dụ về keratin

• These data indicate that these keratin intermediate filament may have a ' hollow ' core.

• It remains to be seen whether this observation is a general one for all intermediate filaments or whether it relates specifically to the trichocyte keratins.

• Conservation of the structure of keratin intermediate filaments : molecular mechanism by which different keratin molecules integrate into preexisting keratin intermediate filaments during differentiation.

• The cellular and molecular biology of keratins: beginning a new era.

• The protein contained a glycinerich region with similarity to host keratins and collagen.

• However, in the 1970s two other sequences, both from sheep wool keratins were characterized.

• So far no discussion has been made of the trichocyte keratins.

• Similarly, in keratinocytes, keratin molecules containing one particular chain pair will ultimately be replaced by molecules comprising a different chain pair as differentiation proceeds.

• The most common were actinrelated and keratin-associated proteins.

• 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.

• Repeating patterns of amino acid residues in the sequences of some high-sulphur proteins from keratin.

• Diversity of intermediate filament structure : evidence that the alignment of coiled-coil molecules in vimentin is different from that in keratin intermediate filaments.

• These may not be inhibited by heavy metals, but are unable to initiate a proper cyst without the presence of the ' keratin-like ' granules.

• A thick layer of keratin develops, to which the patient is usually oblivious, and autolysis takes place underneath.
