Comparative computational analysis of prion proteins reveals two fragments with unusual structural properties and a pattern of increase in hydrophobicity associated with disease-promoting mutations.

Abstract excerpt

Prion diseases are a group of neurodegenerative disorders associated with conversion of a normal prion protein, PrPC, into a pathogenic conformation, PrPSc. The PrPSc is thought to promote the conversion of PrPC. The structure and stability of PrPC are well characterized, whereas little is known about the structure of PrPSc, what parts of PrPC undergo conformational transition, or how mutations facilitate this...
