Yeast prions, mammalian amyloidoses, and the problem of proteomic networks

Yeast prions, mammalian amyloidoses, and the problem of proteomic networks Prion proteins are infective amyloids and cause several neurodegenerative diseases in humans and animals. In yeasts, prions are detected as the cytoplasmic heritable determinants of a protein nature. Yeast prion [PSI], which results from a conformational rearrangement and oligomerization of translation termination factor eRF3, is used as an example to consider the structural-functional relationships in a potentially prion molecule, specifics of its evolution, and interactions with other prions, which form so-called prion networks. In addition, the review considers the results of modeling mammalian prion diseases and other amyloidoses in yeast cells. A hypothesis of proteomic networks is proposed by analogy with prion networks, involving interactions of different amyloids in mammals. Russian Journal of Genetics Springer Journals
