frontotemporal dementia/プロリン

Analysis of 226 exome-sequenced UK cases of familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia identified 2 individuals who harbored a P497H and P506S UBQLN2 mutation, respectively (n = 0.9%). The P506S index case presented with behavioral variant frontotemporal dementia at the

The peptidyl-prolyl cis-trans isomerase (PPIase) Pin1 modulates the activity of a range of target proteins involved in the cell cycle, transcription, translation, endocytosis, and apoptosis by facilitating dephosphorylation of phosphorylated serine or threonine residue preceding a proline

Frontotemporal dementia is a heterogeneous, often inherited disorder that typically presents with the insidious onset of behavioral and personality changes. Two genetic loci have been identified and mutations in tau have been causally implicated in a subset of families linked to one of these loci on

SFPQ (Splicing factor proline- and glutamine-rich) is a DNA and RNA binding protein involved in transcription, pre-mRNA splicing, and DNA damage repair. SFPQ was found dysregulated in a few tauopathies such as Alzheimer's disease (AD) and frontotemporal dementia (FTD). In addition, knock-down of

TAR DNA-binding protein (TDP-43) was identified as the major ubiquitinated component deposited in the inclusion bodies in amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration with ubiquitin-positive inclusions (FTLD-U) in 2006. Later on, numerous ALS-related mutations were found

OBJECTIVE Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease mainly involving cortical and spinal motor neurones. Molecular studies have recently identified different mutations in the ubiquilin-2 (UBQLN2) gene as causative of a familial form of X-linked ALS, 90% penetrant in women.

An intronic hexanucleotide repeat expansion (HRE) mutation in the C9ORF72 gene is the most common cause of familial ALS and frontotemporal dementia (FTD) and is found in ∼7% of individuals with apparently sporadic disease. Several different diamino acid peptides can be generated from the HRE by

A GGGGCC repeat expansion in the C9ORF72 gene has been identified as the most common genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia. The repeat expansion undergoes unconventional translation to produce dipeptide repeat (DPR) proteins. Although it has been reported that

A GGGGCC hexanucleotide repeat expansion in the C9ORF72 gene has been identified as the most common genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia. The repeat expansion undergoes unconventional translation to produce five dipeptide repeat proteins (DPRs). Although DPRs

Expanded GGGGCC (G4C2) nucleotide repeats within the C9ORF72 gene are the most common genetic mutation associated with both amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Sense and antisense transcripts of these expansions are translated to form five dipeptide repeat proteins

OBJECTIVE To describe a new dementia phenotype of Gerstmann-Straussler-Scheinker disease (GSS) in a previously unreported Italian family. Design Longitudinal clinical and neuropsychological assessment, combined with magnetic resonance imaging (MRI), single positron emission tomography (SPECT) and

The tau protein is central to the etiology of several neurodegenerative diseases, including Alzheimer's disease, a subset of frontotemporal dementias, progressive supranuclear palsy and dementia following traumatic brain injury, yet the proteins it interacts with have not been studied using a

Members of the conserved ubiquilin (UBQLN) family of ubiquitin (Ub) chaperones harbor an antipodal UBL (Ub-like)-UBA (Ub-associated) domain arrangement and participate in proteasome and autophagosome-mediated protein degradation. Mutations in a proline-rich-repeat region (PRR) of UBQLN2 cause

A mutation in the ubiquilin 2 gene (UBQLN2) was recently identified as a cause of X-linked amyotrophic lateral sclerosis (ALS)/frontotemporal dementia (FTD) and a major component of the inclusion bodies commonly found with a wide variety of ALS. ALS-linked mutations in UBQLN2 are clustered in a

The casein milk proteins and the brain proteins alpha-synuclein and tau have been described as natively unfolded with random coil structures, which, in the case of alpha-synuclein and tau, have a propensity to form the fibrils found in a number of neurodegenerative diseases. New insight into the
