Neurokeratin
Neu`ro`ker´a`tin

The proteinaceous network that remains of the myelin sheath of axons after fixation and the removal of the fatty material; the reticular appearance is probably a fixation artifact. 2. The insoluble protein matter of brain remaining after extraction with solvents after proteolytic digestion; it is unrelated to the keratins. Synonym(s): neurochitin [neuro- + G. keras, horn] neurokeratin (nū″rō-kĕr′ă-tĭn) [″ + keras, horn] The type of keratin found in myelinated nerve fibers. |
