Sample GSM4557947 Query DataSets for GSM4557947
Status Public on May 19, 2020
Title SIR3-EBD G2_no_estradiol input rep. 1
Sample type SRA
 
Source name Saccharomyces cerevisiae
Organism Saccharomyces cerevisiae
Characteristics strain: JRY12169
chip antibody: None
condition: G1 (alpha factor) arrest followed by release to G2/M (nocodazole) and addition of ethanol (solvent control) for 3 hours
genotype: mat{delta} hml{delta}::HML* bar1{delta} SIR4-13xMyc; SIR3-EBD78
Treatment protocol For SIR3-EBD cultures, estradiol was used at 50 µM. "No estradiol" samples were grown with 0.5% ethanol (solvent control). For G1 arrests, 10 nM alpha factor was added. For G2/M arrests, 15 µg/mL nocodazole was added.
Growth protocol Yeast were cultured at 37° in YPD.
Extracted molecule genomic DNA
Extraction protocol Cells were lysed by mechanical disruption in a bead beater. Chromatin was fragmented using either sonication (all H3K79me3 samples) or MNase (all Sir4-myc and Sir3-EBD samples except for a subset fragmented by sonication, noted in the sample title). DNA was purified using Qiagen spin column kit
NEB Ultra II library prep kit
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina NovaSeq 6000
 
Data processing For samples sequenced on the Illumina NovaSeq 6000, FASTQ generation was performed using Illumina Casava v2.2. For samples sequenced on the Illumina Miniseq, FASTQ generation was performed using the Generate FASTQ module of Illumina Local Run Manager
Raw reads were mapped to SacCer3 genome modified to include hml∆::HML* and mat∆ using Bowtie2 with following options: --local --soft-clipped-unmapped-tlen --no-unal --no-mixed --no-discordant
bedgraph files were generated from aligned reads and normalized to the genome-wide median (median excluded subtelomeres, chromosome III, and rDNA). For MNase samples, only reads between 130-180 bp (mononucleosome) were included in bedgraphs.
