Insight into the conserved structural dynamics of the C-terminus of mammal PrPC identifies structural core and possible structural role of pharmacological chaperones

open access: yesPrion, 2023
Misfolding of the prion protein is central to prion disease aetiology. Although understanding the dynamics of the native fold helps to decipher the conformational conversion mechanism, a complete depiction of distal but coupled prion protein sites common

A Sequence-Dependent DNA Condensation Induced by Prion Protein

open access: yesJournal of Nucleic Acids, 2018
Different studies indicated that the prion protein induces hybridization of complementary DNA strands. Cell culture studies showed that the scrapie isoform of prion protein remained bound with the chromosome. In present work, we used an oxazole dye, YOYO,

A quantitative characterization of interaction between prion protein with nucleic acids

open access: yesBiochemistry and Biophysics Reports, 2018
Binding of recombinant prion protein with small highly structured RNAs, prokaryotic and eukaryotic prion protein mRNA pseudoknots, tRNA and polyA has been studied by the change in fluorescence anisotropy of the intrinsic tryptophan groups of the protein.

Sequence features governing aggregation or degradation of prion-like proteins. [PDF]

open access: yesPLoS Genetics, 2018
Enhanced protein aggregation and/or impaired clearance of aggregates can lead to neurodegenerative disorders such as Alzheimer's Disease, Huntington's Disease, and prion diseases.

Prion Protein Amyloidosis

open access: yesBrain Pathology, 1996
The prion protein (PrP) plays an essential role in the pathogenesis of a group of sporadic, genetically determined and infectious fatal degenerative diseases, referred to as “prion diseases”, affecting the central nervous system of humans and other mammals. The cellular PrP is encoded by a single copy gene, highly conserved across mammalian species. In

Prion protein scrapie and the normal cellular prion protein [PDF]

open access: yesPrion, 2015
Prions are infectious proteins and over the past few decades, some prions have become renowned for their causative role in several neurodegenerative diseases in animals and humans. Since their discovery, the mechanisms and mode of transmission and molecular structure of prions have begun to be established. There is, however, still much to be elucidated

Pathogenic mutations in the hydrophobic core of the human prion protein can promote structural instability and misfolding [PDF]

open access: yes, 2010
Transmissible spongiform encephalopathies, or prion diseases, are caused by misfolding and aggregation of the prion protein PrP. These diseases can be hereditary in humans and four of the many disease-associated missense mutants of PrP are in the ...

Molecular Barriers to Zoonotic Transmission of Prions

open access: yesEmerging Infectious Diseases, 2014
The risks posed to human health by individual animal prion diseases cannot be determined a priori and are difficult to address empirically. The fundamental event in prion disease pathogenesis is thought to be the seeded conversion of normal prion protein

Prion degradation pathways: Potential for therapeutic intervention [PDF]

open access: yes, 2015
Prion diseases are fatal neurodegenerative disorders. Pathology is closely linked to the misfolding of native cellular PrP(C) into the disease-associated form PrP(Sc) that accumulates in the brain as disease progresses. Although treatments have yet to be

Potential Therapeutic Use of Stem Cells for Prion Diseases

open access: yesCells, 2023
Prion diseases are neurodegenerative disorders that are progressive, incurable, and deadly. The prion consists of PrPSc, the misfolded pathogenic isoform of the cellular prion protein (PrPC).
