It is crucial for organisms to be able to control which genes are expressed in which cells and when. Naturally occurring chemical modifications of DNA-binding histone proteins are believed to play an important role in this process; however, it had been unclear whether they play a causal role in instructing gene expression.

Researchers have discovered that in thale cresses histone H3 lysine-9 methylation, conventionally thought to be a mark of turning off gene transcription, can also turn on gene expression via ... For the first time, researchers have developed a genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's ...
Researchers have identified a gene that is crucial for the proper development of photoreceptor cells in the retina. The gene works by regulating microexons, tiny fragments of DNA that play an ... Scientists have observed changes to the gene-regulating factors during zebrafish development and discovered that modifications to 'histone H3', one of the proteins around which DNA is bound, play an ...Will EEG Be Able to Read Your Dreams?
