| Summary |
Snt2 is a yeast chromatin-interacting protein whose function has not been well characterized, that was recently shown to associate with Ecm5 and the Rpd3 deacetylase. Using chromatin immunoprecipitation followed by high-throughput sequencing (ChIP-seq), we show that in response to H2O2, Snt2 and Ecm5 colocalize to promoters of genes involved in various aspects of the environmental stress response. By integrating these ChIP-seq results with expression analysis, we identify a key set of target genes that require Snt2 for proper expression after H2O2 stress. Finally, by mapping Snt2 and Ecm5 localization before and after rapamycin treatment, we identify a subset of H2O2-specific Snt2 and Ecm5 target promoters that are also targeted in response to rapamycin. Our results establish a function for Snt2 in regulating transcriptional changes in response to oxidative stress, and suggest Snt2 may have a role in additional stress pathways.

| Overall design |
Crosslinking ChIP analysis to identify sites of Snt2 or Ecm5 genomic localization before, 0.5 hours after, or 4 hours after treatment with rapamycin (final concentration 5 nM) or with DMSO as a control. Snt2 and Ecm5 were genomically tagged with a 13Myc tag at their C termini. ChIPs were performed using a Myc antibody on either Snt2-Myc or Ecm5-Myc strains, or on untagged wildtype strain (BY4741) as a control. Inputs and ChIPs from untagged strain were sequenced as controls.
