ChIP-Seq for Yrr1 protein on Saccharomyces cerevisiae cells carrying different YRR1 alleles in response to 4-nitroquinoline-N-oxide (4NQO)

In this study, we constructed three isogenic strains of S96 yrr1? background (its native YRR1 gene was knocked out) carrying three different YRR1 alleles, YRR1_S96, YRR1_YJM789, YRR1_S96-I775E, respectively. We then conducted chromatin immuno-precipitation followed by high-throughput sequencing (ChIP-Seq) for Yrr1 protein on the three strains grown in Yeast Peptone Dextrose medium (YPD) and YPD + 4NQO. Overall design: ChIP-Seq for Yrr1 protein was performed in biological triplicates on S96 cells carrying three different YRR1 alleles grown in YPD and YPD + 4NQO. Immune-precipitated DNA were sequenced for all the three cultures and input genomic DNA was sequenced for one culture.
