Abstract

Four protein-based genetic determinants or prions—[ SWI + ], [ MCA ], [ OCT + ], and [ MOT3 + ]—are recent additions to the list of well-known Saccharomyces cerevisiae prions, [ PSI + ], [ URE3 ], and [ PIN + ]. A rapid expansion of this list may indicate that many yeast proteins can convert into heritable prion forms and underscores a problem of prion input into cellular physiology. Here, we prove that the global transcriptional regulator Sfp1 can become a prion corresponding to the prion-like determinant [ ISP + ] described earlier. We show that SFP1 deletion causes an irreversible [ ISP + ] loss, whereas increased SFP1 expression induces [ ISP + ] appearance. Cells that display the [ ISP + ] phenotype contain the aggregated form of Sfp1. Indeed, these aggregates demonstrate a nuclear location. We also show that the phenotypic manifestation of Sfp1 prionization differs from the manifestation of SFP1 deletion. These properties and others distinguish [ ISP + ] from yeast prions described to date.
