Polyglutamine Repeats in Viruses [PDF]

open access: yesMolecular Neurobiology, 2018
This review explores the presence and functions of polyglutamine (polyQ) in viral proteins. In mammals, mutations in polyQ segments (and CAG repeats at the nucleotide level) have been linked to neural disorders and ataxias. PolyQ regions in normal human proteins have documented functional roles, in transcription factors and, more recently, in ...

Solubilization and disaggregation of polyglutamine peptides [PDF]

open access: greenProtein Science, 2001
AbstractA method is described for dissolving and disaggregating chemically synthesized polyglutamine peptides. Polyglutamine peptides longer than about Q20 have been reported to be insoluble in water, but dissolution in – and evaporation from ‐ a mixture of trifluoroacetic acid and hexafluoroisopropanol converts polyglutamine peptides up to at least ...

Hosting Neurotoxicity in Polyglutamine Disease [PDF]

open access: yesCell, 2006
Polyglutamine diseases are caused by an expanded glutamine domain thought to confer a toxic activity onto the respective disease proteins. In this issue, propose that toxicity of the polyglutamine protein Ataxin-1 may not be due to abberant protein interactions mediated by the polyglutamine expansion.

Autophagy and polyglutamine diseases

open access: yesProgress in Neurobiology, 2012
In polyglutamine diseases, an abnormally elongated polyglutamine tract results in protein misfolding and accumulation of intracellular aggregates. The length of the polyglutamine expansion correlates with the tendency of the mutant protein to aggregate, as well as with neuronal toxicity and earlier disease onset.

The Missing Link in Polyglutamine Diseases [PDF]

open access: yesMovement Disorders Clinical Practice, 2017
Polyglutamine diseases are a group of nine hereditary neurodegenerative disorders and include Huntington disease (HD), the most prevalent spinocerebellar ataxias (SCAs type 1, 2, 3, 6, 7 and 17), dentatorubral-pallidoluysian atrophy and spinal and bulbar muscular atrophy (also known as Kennedy disease).

Polyglutamine tracts regulate beclin 1-dependent autophagy

open access: yesNature, 2017
Nine neurodegenerative diseases are caused by expanded polyglutamine (polyQ) tracts in different proteins, such as huntingtin in Huntington’s disease and ataxin 3 in spinocerebellar ataxia type 3 (SCA3).

Ubiquitin-interacting motifs of ataxin-3 regulate its polyglutamine toxicity through Hsc70-4-dependent aggregation

open access: yeseLife, 2020
Spinocerebellar ataxia type 3 (SCA3) belongs to the family of polyglutamine neurodegenerations. Each disorder stems from the abnormal lengthening of a glutamine repeat in a different protein. Although caused by a similar mutation, polyglutamine disorders

Are Polyglutamine Diseases Expanding? [PDF]

open access: yesNeuron, 2011
It remains a matter of speculation as to whether the sense CUG-containing RNA and/or the antisense CAG-encoding polyglutamine peptide serves as the pathogenic moiety in Huntington's disease like-2 (HDL2). In this issue of Neuron, Wilburn et al. show that in a HDL2 mouse model, the polyglutamine peptide drives disease progression.

d-Polyglutamine Amyloid Recruits l-Polyglutamine Monomers and Kills Cells [PDF]

open access: yesJournal of Molecular Biology, 2014
Polyglutamine (polyQ) amyloid fibrils are observed in disease tissue and have been implicated as toxic agents responsible for neurodegeneration in expanded CAG repeat diseases such as Huntington's disease. Despite intensive efforts, the mechanism of amyloid toxicity remains unknown. As a novel approach to probing polyQ toxicity, we investigate here how

Genetics, Mechanisms, and Therapeutic Progress in Polyglutamine Spinocerebellar Ataxias

open access: yesNeurotherapeutics, 2019
Autosomal dominant cerebellar ataxias (ADCAs) are a group of neurodegenerative disorders characterized by degeneration of the cerebellum and its connections.
