p62/SQSTM1 forms protein aggregates degraded by autophagy and has a protective effect on huntingtin-induced cell death

open access: yesJournal of Cell Biology, 2005
Autophagic degradation of ubiquitinated protein aggregates is important for cell survival, but it is not known how the autophagic machinery recognizes such aggregates.

Huntingtin is required for ER-to-Golgi transport and for secretory vesicle fusion at the plasma membrane

open access: yesDisease Models & Mechanisms, 2014
Huntingtin is a large membrane-associated scaffolding protein that associates with endocytic and exocytic vesicles and modulates their trafficking along cytoskeletal tracks. Although the progression of Huntington’s disease is linked to toxic accumulation

Targeting Huntingtin Expression in Patients with Huntington's Disease.

open access: yesNew England Journal of Medicine, 2019
BACKGROUND Huntington's disease is an autosomal-dominant neurodegenerative disease caused by CAG trinucleotide repeat expansion in HTT, resulting in a mutant huntingtin protein.

Mutant huntingtin and neurofilament light have distinct longitudinal dynamics in Huntington’s disease

open access: yesScience Translational Medicine, 2020
Longitudinal analysis in 80 patients shows that mutant huntingtin and neurofilament light could predict Huntington’s disease progression. Protein dynamics in HD Huntington’s disease (HD) is a neurodegenerative disorder caused by mutations in the ...

Mutations causing Lopes-Maciel-Rodan Syndrome are huntingtin hypomorphs.

open access: yesHuman Molecular Genetics, 2021
Huntington's disease (HD) pathogenesis involves a genetic gain-of-function toxicity mechanism triggered by the expanded HTT CAG repeat. Current therapeutic efforts aim to suppress expression of total or mutant huntingtin, though the relationship of ...

A Huntingtin Peptide Inhibits PolyQ-Huntingtin Associated Defects

open access: yesPLoS ONE, 2013
Huntington's disease (HD) is caused by the abnormal expansion of the polyglutamine tract in the human Huntingtin protein (polyQ-hHtt). Although this mutation behaves dominantly, huntingtin loss of function also contributes to HD pathogenesis. Indeed, wild-type Huntingtin plays a protective role with respect to polyQ-hHtt induced defects.The question ...

Inducible mutant huntingtin expression in HN10 cells reproduces Huntington's disease-like neuronal dysfunction

open access: yesMolecular Neurodegeneration, 2009
Background Expansion of a polyglutamine repeat at the amino-terminus of huntingtin is the probable cause for Huntington's disease, a lethal progressive autosomal-dominant neurodegenerative disorders characterized by impaired motor performance and severe ...

Pathogenic Huntingtin Repeat Expansions in Patients with Frontotemporal Dementia and Amyotrophic Lateral Sclerosis.

open access: yesNeuron, 2020
We examined the role of repeat expansions in the pathogenesis of frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS) by analyzing whole-genome sequence data from 2,442 FTD/ALS patients, 2,599 Lewy body dementia (LBD) patients, and 3,158

Huntingtin Regulates Mammary Stem Cell Division and Differentiation

open access: yesStem Cell Reports, 2014
Little is known about the mechanisms of mitotic spindle orientation during mammary gland morphogenesis. Here, we report the presence of huntingtin, the protein mutated in Huntington’s disease, in mouse mammary basal and luminal cells throughout ...
