Abstract
We developed a method for site-selective CpG methylation of the budding yeast genome. The method recruits LexA-fused M.SssI DNA methyltransferase to LexA operator sequences integrated adjacent to the target site. Microarray analysis of methylated DNAs indicated that the tethered enzyme selectively methylates the region around the target site. Exploiting this method to methylate bait DNA in the one-hybrid system, we demonstrated methylation-dependent DNA binding of methyl-CpG binding proteins, MBD1 and Kaiso, in vivo. This methylation-dependent one-hybrid system would provide a versatile tool for the search and analysis of proteins that recognize methylated DNA to participate in epigenetic regulation.
