sapiens 92-102 22178474-3 2012 We describe here the use of very short polyQ repeat lengths in htt N-terminal fragments to slow this disease-associated aggregation. polyglutamine 39-44 huntingtin Homo sapiens 63-66 22178478-3 2012 In this mechanism, the htt(NT) segment forms the alpha-helix-rich core of the oligomers, leaving much of the polyglutamine (polyQ) segment disordered and solvent-exposed. polyglutamine 109-122 huntingtin Homo sapiens 23-26 22178478-3 2012 In this mechanism, the htt(NT) segment forms the alpha-helix-rich core of the oligomers, leaving much of the polyglutamine (polyQ) segment disordered and solvent-exposed. polyglutamine 124-129 huntingtin Homo sapiens 23-26 22178478-8 2012 In the other class, nucleation is actively suppressed by a proline-rich polyQ segment covalently attached to htt(NT). polyglutamine 72-77 huntingtin Homo sapiens 109-112 22178474-1 2012 The 17-amino-acid N-terminal segment (htt(NT)) that leads into the polyglutamine (polyQ) segment in the Huntington"s disease protein huntingtin (htt) dramatically increases aggregation rates and changes the aggregation mechanism, compared to a simple polyQ peptide of similar length. polyglutamine 67-80 huntingtin Homo sapiens 38-41 22178474-1 2012 The 17-amino-acid N-terminal segment (htt(NT)) that leads into the polyglutamine (polyQ) segment in the Huntington"s disease protein huntingtin (htt) dramatically increases aggregation rates and changes the aggregation mechanism, compared to a simple polyQ peptide of similar length. polyglutamine 67-80 huntingtin Homo sapiens 133-143 22178474-1 2012 The 17-amino-acid N-terminal segment (htt(NT)) that leads into the polyglutamine (polyQ) segment in the Huntington"s disease protein huntingtin (htt) dramatically increases aggregation rates and changes the aggregation mechanism, compared to a simple polyQ peptide of similar length. polyglutamine 67-80 huntingtin Homo sapiens 145-148 22178474-2 2012 With polyQ segments near or above the pathological repeat length threshold of about 37, aggregation of htt N-terminal fragments is so rapid that it is difficult to tease out mechanistic details. polyglutamine 5-10 huntingtin Homo sapiens 103-106 23050151-1 2012 Huntington"s disease is a progressive neurodegenerative disease, caused by a polyglutamine expansion in the huntingtin protein. polyglutamine 77-90 huntingtin Homo sapiens 108-118 22334892-4 2012 HD is caused by an expanded polyglutamine repeat in the huntingtin (Htt) protein that actuates a diverse set of pathogenic mechanisms. polyglutamine 28-41 huntingtin Homo sapiens 56-66 22334892-4 2012 HD is caused by an expanded polyglutamine repeat in the huntingtin (Htt) protein that actuates a diverse set of pathogenic mechanisms. polyglutamine 28-41 huntingtin Homo sapiens 68-71 22110140-1 2012 Huntington disease (HD), a fatal neurodegenerative disorder, is caused by a lengthening of the polyglutamine tract in the huntingtin (Htt) protein. polyglutamine 95-108 huntingtin Homo sapiens 122-132 22110140-1 2012 Huntington disease (HD), a fatal neurodegenerative disorder, is caused by a lengthening of the polyglutamine tract in the huntingtin (Htt) protein. polyglutamine 95-108 huntingtin Homo sapiens 134-137 23560309-2 2012 Despite the disease being caused by dysfunction ofa single gene, expressed as an expanded polyglutamine in the huntingtin protein, there is a major variability in the symptom profile of patients with Huntington"s disease as well as great variability in the neuropathology. polyglutamine 90-103 huntingtin Homo sapiens 111-121 23050151-2 2012 A prominent hallmark of the disease is the presence of intracellular aggregates initiated by N-terminal huntingtin fragments containing the polyglutamine repeat, which recruit components of the ubiquitin-proteasome system. polyglutamine 140-153 huntingtin Homo sapiens 104-114 22292820-1 2012 Huntington"s disease (HD) is caused by expansion of a polyglutamine repeat in the N-terminal region of huntingtin (htt), a large protein that has been found to interact with a variety of proteins. polyglutamine 54-67 huntingtin Homo sapiens 103-113 22292820-1 2012 Huntington"s disease (HD) is caused by expansion of a polyglutamine repeat in the N-terminal region of huntingtin (htt), a large protein that has been found to interact with a variety of proteins. polyglutamine 54-67 huntingtin Homo sapiens 115-118 23339311-1 2012 Huntington"s disease arises from CAG codon-repeat expansions in the Htt gene, which leads to a Htt gene product with an expanded polyglutamine

years since the genetic basis for HD was identified, our knowledge of how polyQ-expanded Htt fragment aggregation relates to disease mechanisms remains fragmentary and controversial. polyglutamine 94-99 huntingtin Homo sapiens 109-112 23339311-6 2012 This review discusses these issues in light of a historic summary of Htt aggregation in the cellular milieu and the intrinsic attributes of polyQ-expanded Htt that lead to aggregation. polyglutamine 140-145 huntingtin Homo sapiens 155-158
