| Title |
Genome-wide binding of the cohesin protector Sgo1 in the presence and absence of the meiosis I-specific Spo13 protein |
| Organism |
Saccharomyces cerevisiae |
| Experiment type |
Genome binding/occupancy profiling by high throughput sequencing
|
| Summary |
ChIP-seq profile of Sgo1 binding sites arrested in metaphase I by deletion of the APC/C activator CDC20. The aim of this experiment is to identify whether Sgo1 binding differs in wild type cells and cells deficient of the meiosis I-specific protein Spo13, which is required for retention of pericentromeric cohesin after metaphase I.

| Overall design |
Diploid S. cerevisiae SK1 cells were constructed containing Sgo1-6Ha in an pGAL1-NDT80 pGPD1-GAL4.ER pCLB2-CDC20 background. Cells were allowed to sporulate in sporulation media for 5 hours before addition of β-estradiol to release from prophase arrest. Cells were grown for 75min to arrest in metaphase I after which formaldehyde was added to the cultures and cells were fixed for 30min. We chose this double-arrest strategy (with a prophase I arrest followed by a metaphase I arrest) to ensure efficient arrest in metaphase I, which is less robust in cells without Spo13. Samples were subsequently processed according to the standard lab ChIP-Seq protocol.
