1 Huntingtin with an expanded polyglutamine repeat affects the Jab1-p27(Kip1) pathway. polyglutamine COP9 signalosome subunit 5 Homo sapiens
2 In this study, we report on a novel target of expanded polyglutamine stretches, the transcriptional coactivator Jun activation domain-binding protein 1 (Jab1), which shares DNA-sequence-specific transcription factor targets with CBP. polyglutamine COP9 signalosome subunit 5 Homo sapiens
3 In this study, we report on a novel target of expanded polyglutamine stretches, the transcriptional coactivator Jun activation domain-binding protein 1 (Jab1), which shares DNA-sequence-specific transcription factor targets with CBP. polyglutamine COP9 signalosome subunit 5 Homo sapiens
4 We found that Jab1 accumulates in aggregates when co-expressed with either expanded polyglutamine stretches or N-terminal fragments of mutant htt. polyglutamine COP9 signalosome subunit 5 Homo sapiens
5 In addition, the coactivator function of Jab1 was suppressed both by aggregated expanded polyglutamine solely and by mutant htt. polyglutamine COP9 signalosome subunit 5 Homo sapiens
