[Yeast as a model for studying the prion and amyloid occurrence]
Abstract:
Recent data on the use of yeast as a model for studying the molecular basis of prion infection are summarized. In contrast to mammalian prions, which are related to incurable neurodegenerative diseases, yeast prions determine the appearance of non-chromosomally inherited phenotypic traits. Prions of yeast are structurally similar to amyloids of mammals and their replication involves not only growth, but also fragmentation of prion amyloid-like fibrils. In mammals the fragmentation should lead to an increase in infectious titer. The use of yeast for study of the mechanisms of human amyloidoses, development of new anti-prion drugs and search for new proteins with prion properties is described.
