1 We show, in vitro and in cells, that monomers or small soluble oligomers of huntingtin exon1 accumulate in the nucleus and inhibit the function of TBP in a polyQ-dependent manner. polyglutamine TATA-box binding protein Homo sapiens
2 Interaction of toxic huntingtin with the benign polyQ repeat of TBP structurally destabilizes the transcription factor, independent of the formation of insoluble coaggregates. polyglutamine TATA-box binding protein Homo sapiens
