ABSTRACT: RNA polymerases deal with obstacles during transcription elongation that need to be removed. One important type of hindrance consists of DNA lesions, which are removed by transcription-coupled repair (TCR). To improve our knowledge of transcription elongation and its coupling to TCR, we performed DNA microarray experiments and used the yeast library of nonessential knock-out mutations to screen for genes conferring resistance to the transcription-elongation inhibitor micophenolic acid and the DNA-damaging agent 4- nitroquinoline-N-oxide. A single sample for each treatment was analyzed.

RNA polymerases frequently deal with a number of obstacles during transcription elongation that need to be removed for transcription resumption. One important type of hindrance consists of DNA lesions, which are removed by transcription-coupled repair (TC-NER), a specific sub-pathway of nucleotide excision repair. To improve our knowledge of transcription elongation and its coupling to TC-NER, we used the yeast library of non-essential knock-out mutations to screen for genes conferring resistanc  ...[more]
