Gene regulatory mechanisms downstream of DNA methylation.

Specialized reader proteins and transcription factors interpret DNA methylation to regulate gene expression and chromatin structure in mammals and plants.

• Why it matters: Understanding how DNA methylation influences transcriptional programs is crucial for deciphering epigenetic regulation in development, differentiation, and disease, yet downstream mechanisms remain poorly characterized.
• What they did: The authors review current knowledge on how methylation-dependent reader proteins and transcription factors preserve methylation patterns, recruit effector complexes, and interact with other epigenetic systems, based on studies across diverse eukaryotes.
• The result: These layered and redundant mechanisms underpin stable transcriptional and epigenetic states, providing a framework for future research into epigenome regulation and its implications for health and disease.
