Laccaic acid A is a direct, DNA-competitive inhibitor of DNA methyltransferase 1.

Methylation of cytosines in CpG dinucleotides is the predominant epigenetic mark on vertebrate DNA. DNA methylation is associated with transcriptional repression. The pattern of DNA methylation changes during development and with disease. Human DNA methyltransferase 1 (Dnmt1), a 1616-amino acid multidomain enzyme, is essential for maintenance of DNA methylation in proliferating cells and is con...

TFIIIC Boxes in the Genome

In this issue of Cell, Noma et al. (2006) show that B-boxes and TFIIIC limit the spread of heterochromatin at the silent mat region in the fission yeast genome. Global analysis of TFIIIC distribution revealed dispersed sites of association that coalesce at the nuclear periphery, suggesting that TFIIIC may act as a barrier throughout the genome.
