The formation of heterochromatin at HML, HMR, and telomeres in Saccharomyces cerevisiae involves two main steps: Recruitment of Sir proteins to silencers and their spread throughout the silenced domain. For the following datasets, we created a fusion protein between the heterochromatin protein Sir3 and the non-site-specific bacterial adenine methyltransferase M.EcoGII. We mapped sites of Sir3-chromatin interactions genome-wide using long-read Nanopore sequencing to detect adenines methylated by the fusion protein. We also used a temperature-sensitive allele of SIR3 (sir3-8) fused to M.ECOGII to induce m6A methylation over time. Time courses involved a switch from restrictive temperature (37°C) to permissive temperature (25°C). Overall design: 29 samples total. Replicates of each experiment are included (indicated by multiple samples of the same genotype and condition). Less...
