A tumor-suppressing protein acts as a dimmer switch to dial down gene expression. It does this by reading a chemical message attached to another protein that's tightly intertwined with DNA, a team of scientists have learned. The findings of this study provide evidence in support of the "histone code" hypothesis. The theory holds that histone proteins, which combine with DNA to form chromosomes, are more intimately involved in gene expression than their general role of facilitating or hindering g...
