Infectious amyloid filaments designated as prion rods or scrapie associated fibrils (SAF) present in brain tissues affected by transmissible spongiform encephalopathies such as Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scheinker disease (GSS) and kuru of humans, and scrapie of sheep. A hydrophobic glycoprotein, PrPSc is a major component of SAF, and is known to be associated with the infectivity of these diseases. Both PrPSc and the normal isoform of this glycoprotein, PrPC are encoded by a single host gene, PrP gene, and the conversion of PrPC to PrPSc is a posttranslational event. Several mutations on the PrP gene are associated with variations of the phenotype and the occurrence in familial CJD and GSS.
