Prions represent an unusual structural form of a protein that is ‘infectious’. In mammals, prions are associated with fatal neurodegenerative diseases such as CJD (Creutzfeldt–Jakob disease), while in fungi they act as novel epigenetic regulators of phenotype. Even though most of the human prion diseases arise spontaneously, we still know remarkably little about how infectious prions formde novo. The [PSI+] prion of the yeastSaccharomyces cerevisiaeprovides a highly tractable model in which to explore the underlying mechanism ofde novoprion formation, in particular identifying keycis- andtrans-acting factors. Most significantly, thede novoformation of [PSI+] requires the presence of a second prion called [PIN+], which is typically the prion form of Rnq1p, a protein rich in glutamine and aspartic acid residues. The molecular mechanism by which the [PIN+] prion facilitatesde novo[PSI+] formation is not fully established, but most probably involves some form of cross-seeding. A number of other cellular factors, in particular chaperones of the Hsp70 (heat-shock protein 70) family, are known to modify the frequency ofde novoprion formation in yeast.
