Sonication Induced Intermediate in Prion Protein Conversion
We have observed that hamster prion protein (PrPC) 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 (PrPSc) 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 PrPC to PrPSc.

Publication date: 01 February 2008
- Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
