Molecular mechanisms of proteinopathies across neurodegenerative disease: a review
Background Although there is a range of different symptoms across neurodegenerative diseases, they have been noted to have common pathogenic features.

Protein folding disorders: Toward a basic biological paradigm [PDF]
Mechanistic 'physics' models of protein folding fail to account for the observed spectrum of protein folding and aggregation disorders, suggesting that a more appropriately biological paradigm will be needed for understanding the etiology ...

Nanomedicine and protein misfolding diseases [PDF]
Misfolding and self assembly of proteins in nano-aggregates of different sizes and morphologies (nano-ensembles, primarily nanofilaments and nano-rings) is a complex phenomenon that can be facilitated, impeded, or prevented, by interactions with various intracellular metabolites, intracellular nanomachines controlling protein folding and interactions ...

Impaired Cleavage of Preproinsulin Signal Peptide Linked to Autosomal-Dominant Diabetes [PDF]
Recently, missense mutations upstream of preproinsulin’s signal peptide (SP) cleavage site were reported to cause mutant INS gene-induced diabetes of youth (MIDY).

Methionine 129 variant of human prion protein oligomerizes more rapidly than the valine 129 variant - Implications for disease susceptibility to Creutzfeldt-Jakob disease [PDF]
The human PrP gene (PRNP) has two common alleles that encode either methionine or valine at codon 129. This polymorphism modulates disease susceptibility and phenotype of human transmissible spongiform encyphalopathies, but the molecular mechanism by ...

Huntington’s disease (HD) is caused by misfolding of mutant Htt protein. The authors find that in HD models, the decreased expression of heat shock transcription factor 1 that usually protects against protein misfolding, is in part caused by elevated ...

Estrogens promote misfolded proinsulin degradation to protect insulin production and delay diabetes [PDF]
Summary: Conjugated estrogens (CE) delay the onset of type 2 diabetes (T2D) in postmenopausal women, but the mechanism is unclear. In T2D, the endoplasmic reticulum (ER) fails to promote proinsulin folding and, in failing to do so, promotes ER stress and

Theoretical model of prion propagation: A misfolded protein induces misfolding [PDF]
There is a hypothesis that dangerous diseases such as bovine spongiform encephalopathy, Creutzfeldt-Jakob, Alzheimer's, fatal familial insomnia, and several others are induced by propagation of wrong or misfolded conformations of some vital proteins. If for some reason the misfolded conformations were acquired by many such protein molecules it might ...

Interaction of tau with the RNA-Binding Protein TIA1 Regulates tau Pathophysiology and Toxicity
Summary: Dendritic mislocalization of microtubule associated protein tau is a hallmark of tauopathies, but the role of dendritic tau is unknown. We now report that tau interacts with the RNA-binding protein (RBP) TIA1 in brain tissue, and we present the ...
