DNA Methylation and Chromatin Organization

DNA methylation is closely connected to chromatin structure and histone modifications.

Methylated DNA can recruit proteins that interact with histone-modifying enzymes, facilitating the establishment of chromatin environments associated with transcriptional repression.

For example, interactions between methyl-CpG-binding proteins and histone deacetylase complexes can contribute to reduced histone acetylation and changes in chromatin accessibility.

Histone methylation also participates in this regulatory landscape. Certain modifications, including H3K9me3, are frequently associated with transcriptionally repressive chromatin states.
