摘要：

Yeast prions are atypical genetic elements that are transmitted as heritable protein conformations. [PSI+], [URE3], and [PIN+] are three well-studied prions in the budding yeast, Saccharomyces cerevisiae. In the last three years, several additional prions have been reported in yeast, including [SWI+], [OCT+], [MCA], [GAR(+)], [MOT3(+)], [ISP+], and [NSI+]. The growing number of yeast prions suggests that protein-based inheritance might be a widespread biological phenomenon. In this review, we summarize the characteristics of each prion element, and discuss their potential functional roles in yeast biology. (C) 2011 Elsevier Ltd. All rights reserved.
