Abstract
Amyloids are protein aggregates with a specific filamentous structure that are related to a number of human diseases, and also to some important physiological processes in animals and other kingdoms of life. Amyloids in yeast can stably propagate as heritable units, prions. Yeast prions are of interest both on their own and as a model for amyloids and prions in general. In this review, we consider the structure of yeast prions and its variation, how such structures determine the balance of aggregated and soluble prion protein through interaction with chaperones and how the aggregated state affects the non-prion functions of these proteins.

Abstract
Cellular quiescence is a nonproliferative state required for cell survival under stress and during development. In most quiescent cells, proliferation is stopped in a reversible state of low Cdk1 kinase activity; in many organisms, however, quiescent states with high-Cdk1 activity can also be established through still uncharacterized stress or developmental mechanisms. Here, we used a microfluidics approach coupled to phenotypic classification by machine learning to identify stress pathways associated with starvation-triggered high-Cdk1 quiescent states in Saccharomyces cerevisiae. We found that low- and high-Cdk1 quiescent states shared a core of stress-associated processes, such as autophagy, protein aggregation, and mitochondrial up-regulation, but differed in the nuclear accumulation of the stress transcription factors Xbp1, Gln3, and Sfp1. The decision between low- or high-Cdk1 quiescence was controlled by cell cycle-independent accumulation of Xbp1, which acted as a time-delayed integrator of the duration of stress stimuli. Our results show how cell cycle-independent stress-activated factors promote cellular quiescence outside G1/G0.

Abstract
Amyloids represent protein fibrils with a highly ordered spatial structure, which not only cause dozens of incurable human and animal diseases but also play vital biological roles in Archaea, Bacteria, and Eukarya. Despite the fact that association of bacterial amyloids with microbial pathogenesis and infectious diseases is well known, there is a lack of information concerning the amyloids of symbiotic bacteria. In this study, using the previously developed proteomic method for screening and identification of amyloids (PSIA), we identified amyloidogenic proteins in the proteome of the root nodule bacterium Rhizobium leguminosarum. Among 54 proteins identified, we selected two proteins, RopA and RopB, which are predicted to have β-barrel structure and are likely to be involved in the control of plant-microbial symbiosis. We demonstrated that the full-length RopA and RopB form bona fide amyloid fibrils in vitro. In particular, these fibrils are β-sheet-rich, bind Thioflavin T (ThT), exhibit green birefringence upon staining with Congo Red (CR), and resist treatment with ionic detergents and proteases. The heterologously expressed RopA and RopB intracellularly aggregate in yeast and assemble into amyloid fibrils at the surface of Escherichia coli. The capsules of the R. leguminosarum cells bind CR, exhibit green birefringence, and contain fibrils of RopA and RopB in vivo.

Abstract
The search for novel pathological and functional amyloids represents one of the most important tasks of contemporary biomedicine. Formation of pathological amyloid fibrils in the aging brain causes incurable neurodegenerative disorders such as Alzheimer's, Parkinson's Huntington's diseases. At the same time, a set of amyloids regulates vital processes in archaea, prokaryotes and eukaryotes. Our knowledge of the prevalence and biological significance of amyloids is limited due to the lack of universal methods for their identification. Here, using our original method of proteomic screening PSIA-LC-MALDI, we identified a number of proteins that form amyloid-like detergent-resistant aggregates in Saccharomyces cerevisiae. We revealed in yeast strains of different origin known yeast prions, prion-associated proteins, and a set of proteins whose amyloid properties were not shown before. A substantial number of the identified proteins are cell wall components, suggesting that amyloids may play important roles in the formation of this extracellular protective sheath. Two proteins identified in our screen, Gas1 and Ygp1, involved in biogenesis of the yeast cell wall, were selected for detailed analysis of amyloid properties. We show that Gas1 and Ygp1 demonstrate amyloid properties both in vivo in yeast cells and using the bacteria-based system C-DAG. Taken together, our data show that this proteomic approach is very useful for identification of novel amyloids.

Abstract
The concept of "protein-based inheritance" defines prions as epigenetic determinants that cause several heritable traits in eukaryotic microorganisms, such as Saccharomyces cerevisiae and Podospora anserina. Previously, we discovered a non-chromosomal factor, [NSI+], which possesses the main features of yeast prions, including cytoplasmic infectivity, reversible curability, dominance, and non-Mendelian inheritance in meiosis. This factor causes omnipotent suppression of nonsense mutations in strains of S. cerevisiae bearing a deleted or modified Sup35 N-terminal domain. In this work, we identified protein determinants of [NSI+] using an original method of proteomic screening for prions. The suppression of nonsense mutations in [NSI+] strains is determined by the interaction between [SWI+] and [PIN+] prions. Using genetic and biochemical methods, we showed that [SWI+] is the key determinant of this nonsense suppression, whereas [PIN+] does not cause nonsense suppression by itself but strongly enhances the effect of [SWI+]. We demonstrated that interaction of [SWI+] and [PIN+] causes inactivation of SUP45 gene that leads to nonsense suppression. Our data show that prion interactions may cause heritable traits in Saccharomyces cerevisiae. The data presented in the paper deepens and enriches the concept of protein-based inheritance. According to this concept, prion conformational switches change protein functional activity, and such changes are inherited. Here, for the first time, we demonstrate that heritable traits may appear not only due to a conformational switch of one protein but also can be caused by interactions between different prions. To identify the novel epigenetic factor that causes suppression of nonsense mutations in yeast, we applied our original method of proteomic screening of prions. We have shown that two yeast proteins, which normally do not interact, in prion form demonstrate genetic interaction: one is the key determinant of the suppression of nonsense mutation, while the second enhances this effect. Thus, by analogy with monogenic and polygenic inheritance, in the framework of the prion concept, we can distinguish “monoprionic” and “polyprionic” inheritance. We assume that new examples of polyprionic inheritance will be revealed using modern proteomic methods for identification of prions.
