- Abstract
ATP-dependent chromatin remodeling by the CHD family of proteins plays an important role in the regulation of gene transcription. Here we report that full-length CHD8 interacts directly with beta-catenin and that CHD8 is also recruited specifically to the promoter regions of several beta-catenin-responsive genes. Our results indicate that CHD8 negatively regulates beta-catenin-targeted gene expression, since short hairpin RNA against CHD8 results in the activation of several beta-catenin target genes. This regulation is also conserved through evolution; RNA interference against kismet, the apparent Drosophila ortholog of CHD8, results in a similar activation of beta-catenin target genes. We also report the first demonstration of chromatin remodeling activity for a member of the CHD6-9 family of proteins, suggesting that CHD8 functions in transcription through the ATP-dependent modulation of chromatin structure.
