UAS regulatory sequences drive expression of a DNA fragment carrying the region in intron 9 of Hsap\ATXN10 containing the AUUCU repeat, plus 141 bp of surrounding sequence where a termination codon is inserted immediately upstream of the Hsap\ATXN10 sequences having the effect of moving the 65 interrupted repeats of the penta-nucleotide AUUCU into the 3'-untranslated region of the transcript. The sequence of the repeat tract in this construct is (ATTCT)[[20]] ACTCT (ATTCT)[[23]] ATTCC (ATTCT)[[15]] ATTTT (ATTCT)[[7]].
