Molecular mechanisms of epigenetic gene regulation.
Mammalian DNA methyltransferases catalyze the addition of methyl groups to the carbon 5 of the cytosine ring located within CG dinucleotides. DNA methylation, particularly when applied to CG-rich promoter sequences, has been shown to silence gene expression in a heritable manner. The transcriptional silencing associated with 5-methylcytosine is required for fundamental physiological processes such as embryonic development, protection against intragenomic parasites, X-inactivation and genomic imprinting. In addition, aberrant promoter methylation and inappropriate silencing of tumor suppressor genes has recently emerged as a major cause leading to cancer. We are using a combination of approaches (biochemistry, structural biology, mammalian cell culture) to study the function of DNA methyltransferases in mammalian cells.
