Saccharomyces cerevisiae in neuroscience: how unicellular organism helps to better understand prion protein?

open access: yesNeural Regeneration Research, 2021
The baker’s yeast Saccharomyces (S.) cerevisiae is a single-celled eukaryotic model organism widely used in research on life sciences. Being a unicellular organism, S. cerevisiae has some evident limitations in application to neuroscience. However, yeast

Spreading of a prion domain from cell-to-cell by vesicular transport in Caenorhabditis elegans. [PDF]

open access: yesPLoS Genetics, 2013
Prion proteins can adopt self-propagating alternative conformations that account for the infectious nature of transmissible spongiform encephalopathies (TSEs) and the epigenetic inheritance of certain traits in yeast.

Regulation of MicroRNAs-Mediated Autophagic Flux: A New Regulatory Avenue for Neurodegenerative Diseases With Focus on Prion Diseases

open access: yesFrontiers in Aging Neuroscience, 2018
Prion diseases are fatal neurological disorders affecting various mammalian species including humans. Lack of proper diagnostic tools and non-availability of therapeutic remedies are hindering the control strategies for prion diseases. MicroRNAs (miRNAs)

Dissection and design of yeast prions. [PDF]

open access: yesPLoS Biology, 2004
Many proteins can misfold into beta-sheet-rich, self-seeding polymers (amyloids). Prions are exceptional among such aggregates in that they are also infectious.

Assessing Proteinase K Resistance of Fish Prion Proteins in a Scrapie-Infected Mouse Neuroblastoma Cell Line

open access: yesViruses, 2014
The key event in prion pathogenesis is the structural conversion of the normal cellular protein, PrPC, into an aberrant and partially proteinase K resistant isoform, PrPSc.

Hsp40/JDP Requirements for the Propagation of Synthetic Yeast Prions

open access: yesViruses, 2022
Yeast prions are protein-based transmissible elements, most of which are amyloids. The chaperone protein network in yeast is inexorably linked to the spreading of prions during cell division by fragmentation of amyloid prion aggregates. Specifically, the

Prion-dependent proteome remodeling in response to environmental stress is modulated by prion variant and genetic background

open access: yesPrion, 2019
A number of fungal proteins are capable of adopting multiple alternative, self-perpetuating prion conformations. These prion variants are associated with functional alterations of the prion-forming protein and thus the generation of new, heritable traits

AMYCO: evaluation of mutational impact on prion-like proteins aggregation propensity

open access: yesBMC Bioinformatics, 2019
Background Around 1% of human proteins are predicted to contain a disordered and low complexity prion-like domain (PrLD). Mutations in PrLDs have been shown promote a transition towards an aggregation-prone state in several diseases. Results Recently, we

Computational Analysis of Candidate Prion-Like Proteins in Bacteria and Their Role

open access: yesFrontiers in Microbiology, 2015
Prion proteins were initially associated with diseases such as Creutzfeldt Jakob and transmissible spongiform encephalopathies. However, deeper research revealed them as versatile tools, exploited by the cells to execute fascinating functions, acting as ...

Evolutionary descent of prion genes from the ZIP family of metal ion transporters. [PDF]

open access: yesPLoS ONE, 2009
In the more than twenty years since its discovery, both the phylogenetic origin and cellular function of the prion protein (PrP) have remained enigmatic.
