Abstract excerpt

[URE3] and [PSI] are two non-Mendelian genetic elements discovered over 25 years ago and never assigned to a nucleic acid replicon. Their genetic properties led us to propose that they are prions, altered self-propagating forms of Ure2p and Sup35p, respectively, that cannot properly carry out the normal functions of these proteins. Ure2p is partially protease-resistant in [URE3] strains and Sup35p is aggregated...
