WebDNA methylation and chromatin modification are two global mechanisms that regulate gene expression. Recent studies provide insight into the mechanism of transcriptional silencing by a methyl-CpG binding protein, MeCP2. MeCP2 is shown to interact with the Sin3/histone deacetylase co-repressor complex. WebControl of CpNpG DNA methylation by the kryptonite histone H3 methyltransferase.
