N-methyl-d-aspartate (NMDA) and kainate receptors via postsynaptic density 95 (PSD-95), (ii) the SH3 domain of PSD-95 mediates its binding to huntingtin, and (iii) polyglutamine expansion interferes with the ability of huntingtin to interact with PSD-95. polyglutamine 244-257 huntingtin Homo sapiens 50-60 11319238-6 2001 The expression of polyglutamine-expanded huntingtin causes sensitization of NMDA receptors and promotes neuronal apoptosis induced by glutamate. polyglutamine 18-31 huntingtin Homo sapiens 41-51 11319238-7 2001 The addition of the NMDA receptor antagonist significantly attenuates neuronal toxicity induced by glutamate and polyglutamine-expanded huntingtin. polyglutamine 113-126 huntingtin Homo sapiens 136-146 11319238-9 2001 Our results demonstrate that

10770929-5 2000 In contrast to cleavable htt, caspase-resistant htt with an expanded polyglutamine tract has reduced toxicity in apoptotically stressed neuronal and nonneuronal cells and forms aggregates at a much reduced frequency. polyglutamine 69-82 huntingtin Homo sapiens 48-51 10801775-0 2000 Activation of MLK2-mediated signaling cascades by polyglutamine-expanded huntingtin.

induces JNK activation and apoptosis in HN33 cells. polyglutamine 29-42 huntingtin Homo sapiens 52-62 10801775-9 2000 Our results suggest that activation of MLK2-mediated signaling cascades may be partially involved in neuronal death induced by polyglutamine-expanded huntingtin. polyglutamine 127-140 huntingtin Homo sapiens 150-160 10829068-3 2000 Here we show by using a filter retardation

mutation in patients with Huntington"s disease is an expanded CAG/polyglutamine repeat in huntingtin, a protein of unknown function with a relative molecular mass of 350,000 (M(r) 350K). polyglutamine 70-83 huntingtin Homo sapiens 94-104 10353249-6 1999 Transgenic mice expressing exon 1 of the human huntingtin gene with an expanded CAG/polyglutamine repeat develop a progressive syndrome with many

sapiens 136-146 9679147-6 1998 In some human proteins, e.g., Huntingtin, abnormal amplification of such poly-glutamine regions causes late-onset neurodegeneration. polyglutamine 73-87 huntingtin Homo sapiens 30-40 9682010-2 1998 In patients with Huntington"s disease (HD), the NH2-terminal region of huntingtin has an expanded polyglutamine tract. polyglutamine 98-111 huntingtin Homo sapiens 71-81 10410676-2 1998 It has been proposed that the expanded polyglutamine stretch confers a new property on huntingtin and thereby causes cell and region-specific neurodegeneration. polyglutamine 39-52 huntingtin Homo sapiens 87-97 10410676-3 1998 Genotype-phenotype correlations predict that this novel property appears above a threshold length (approximately 38 glutamines), becomes progressively more evident with increasing polyglutamine length, is completely dominant over normal huntingtin and is not appreciably worsened by a double genetic dose in HD homozygotes. polyglutamine 180-193 huntingtin Homo sapiens 237-247 10410676-11 1998 Our data support the view that the expanded polyglutamine segment confers on huntingtin a new property that plays a determining role in HD pathogenesis and could be a target for treatment. polyglutamine 44-57 huntingtin Homo sapiens 77-87 9606203-6 1998 Furthermore, expression of mutant huntingtin results in increased susceptibility to apoptotic stress that is greater with decreasing protein length and increasing polyglutamine size. polyglutamine 163-176 huntingtin Homo sapiens 34-44 9587422-4 1998 In the presence of tissue transglutaminase, purified glyceraldehyde-3-phosphate dehydrogenase (a key glycolytic enzyme that binds tightly to the polyglutamine domains of both huntingtin and dentatorubral-pallidoluysian atrophy proteins) is covalently attached to polyglutamine peptides in vitro, resulting in the formation of high-M(r) aggregates. polyglutamine 145-158 huntingtin Homo sapiens 175-185 9666478-1 1998 Huntington"s disease (HD) is caused by CAG triplet repeat expansion in IT15 which leads to polyglutamine stretches in the HD protein product, huntingtin. polyglutamine 91-104 huntingtin Homo sapiens 71-75 9527890-2 1998

parts of the brain affected by Huntington"s disease, the amount of the huntingtin with expanded polyglutamine is reduced and there appear huntingtin-containing polymers of larger molecular weight. polyglutamine 99-112 huntingtin Homo sapiens 74-84 9660943-3 1998 We show here that huntingtin is a substrate of transglutaminase in vitro and that the rate constant of the reaction increases with length of the polyglutamine over a range of an order of magnitude. polyglutamine 145-158 huntingtin Homo sapiens 18-28 9660943-4 1998 As a result, huntingtin with expanded polyglutamine is preferentially incorporated into polymers. polyglutamine 38-51 huntingtin Homo sapiens 13-23 9660943-5 1998 Both disappearance of the huntingtin with expanded polyglutamine and its replacement by polymeric forms are prevented by inhibitors of transglutaminase. polyglutamine 51-64 huntingtin Homo sapiens 26-36 10488448-3 1998 The genetic defect causing HD is an expansion of a CAG repeat

we will mainly focus on the mechanisms by which the wild-type huntingtin (HTT) protein helps in DNA repair during transcription, and the how polyglutamine expansions in HTT impedes this process in HD. polyglutamine 254-267 huntingtin Homo sapiens 282-285 35108063-1 2022 Huntington"s disease (HD) is a dominantly inherited neurodegenerative disorder caused by a CAG trinucleotide expansion in the
