Sonication induced intermediate in prion protein conversion.
نویسندگان
چکیده
We have observed that hamster prion protein (PrP(C)) undergoes conformational changes on exposure to heat or sonication. If a sonication induced new conformer is seeded with a small amount of its abnormal pathogenic isoform (PrP(Sc)) it undergoes a significant conversion to a proteinase-resistant isoform. This suggests the presence of a third stable PrP conformer, which may be intermediate in the conversion of PrP(C) to PrP(Sc).

Mechanistic prospective for human PrPC conversion to PrPSc: Molecular dynamic insights
PrPC conversion to PrPSc isoform is the main known cause for prion diseases including Crutzfeldt-Jakob, Gerstmann-Sträussler-Sheinker syndrome and fatal familial insomnia in human. The precise mechanism underling this conversion is yet to be well understood. In the present work, using the coordinate file of PrPC (available on the Protein Data Bank) as a starting structure, separate molecular d...

The conversion of the alpha-helical, cellular isoform of the prion protein (PrP(C)) to the insoluble, beta-sheet-rich, infectious, disease-causing isoform (PrP(Sc)) is the key event in prion diseases. In an earlier study, several forms of PrP were converted into a fibrillar state by using an in vitro conversion system consisting of low concentrations of SDS and 250 mM NaCl. Here, we characteriz...
متن کاملScrapie susceptibility-linked polymorphisms modulate the in vitro conversion of sheep prion protein to protease-resistant forms.
Prion diseases are natural transmissible neurodegenerative disorders in humans and animals. They are characterized by the accumulation of a protease-resistant scrapie-associated prion protein (PrPSc) of the host-encoded cellular prion protein (PrPC) mainly in the central nervous system. Polymorphisms in the PrP gene are linked to differences in susceptibility for prion diseases. The mechanisms ...
متن کاملRole of polysaccharide and lipid in lipopolysaccharide induced prion protein conversion
Conversion of native cellular prion protein (PrPc) from an α-helical structure to a toxic and infectious β-sheet structure (PrPSc) is a critical step in the development of prion disease. There are some indications that the formation of PrPSc is preceded by a β-sheet rich PrP (PrPβ) form which is non-infectious, but is an intermediate in the formation of infectious PrPSc. Furthermore the presenc...
متن کاملUse of bovine recombinant prion protein and real-time quaking-induced conversion to detect cattle transmissible mink encephalopathy prions and discriminate classical and atypical L- and H-Type bovine spongiform encephalopathy
Prions are amyloid-forming proteins that cause transmissible spongiform encephalopathies through a process involving conversion from the normal cellular prion protein to the pathogenic misfolded conformation (PrPSc). This conversion has been used for in vitro assays including serial protein misfolding amplification and real-time quaking induced conversion (RT-QuIC). RT-QuIC can be used for the ...
