| Title |
Nup170-myc ChIP from yku70∆ cells |
| Sample type |
genomic |
| |
|
| Channel 1 |
| Source name |
Nup170-myc ChIP from yku70∆ cells, ChIP
|
| Organism |
Saccharomyces cerevisiae |
| Characteristics |
chip antibody: anti-Myc monoclonal antibody (cat# 9E10; Roche)
strain: YWY1502 (MATa his3∆1 leu2∆0 ura3∆0 lys2∆0 NUP170-9xMYC::hphR yku70∆::natR)
|
| Growth protocol |
Yeast strains were cultured at 30˚C in YPD medium to an OD600 of 1.0 and proteins were cross-linked to their respective DNA binding sites with 1% formaldehyde for 1 h at room temperature and the cross-linking reaction was quenched by incubation with 125 mM glycine for 5 min prior to harvesting of cells.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
Chromatin immunoprecipitations were performed as described by Smith et al., 2007 with modifications according to Wan et al., 2009. Cells were disrupted by glass bead lysis and chromatin was sheared to an average size of 400 bp. Myc-tagged fusion proteins were purified using 2 μg of α-Myc antibody (9E10; Roche) prebound to 50 μl of Dynabead Pan Mouse IgG magnetic beads (Invitrogen) and incubated with sheared chromatin lysate containing 1 mg of protein overnight at 4˚C. Crosslinks were reversed in ChIP and whole cell lysate fractions and purified samples were analyzed by DNA microarrays.

| Description |
Genome-wide localization of Nup170-9xMyc in yku70∆ cells
|
| Data processing |
Data extraction was performed using the Agilent Feature Extraction software. Bound probes were analyzed by the Agilent ChIP Analytics software according to the neighborhood model. In the neighborhood model, a probe to be considered as significantly bound was required to pass the following filters: 1) the candidate bound probe has a p-value ≤ 0.05, and 2) the central probe has a p-value ≤ 0.05 or at least one neighboring probe has a p-value ≤ 0.25. The purpose of neighborhood model is to identify which probes are most representative of binding events.
