Polycomb-mediated repression and DNA methylation are important epigenetic mechanisms of gene silencing. Recent evidence suggests a functional link between the polycomb repressive complex (PRC) and Dnmts in cancer cells. Here we provide evidence that Lsh, a regulator of DNA methylation, is also involved in normal control of PRC-mediated silencing during embryogenesis. We demonstrate that Lsh, a SNF2 homolog, can associate with some Hox genes and regulates Dnmt3b binding, DNA methylation, and sile ...[more]
