...hromosomes. In many cases, when the DNA is tightly wrapped around the histones, the genes cannot be accessed and their expression is repressed. When the coils of DNA around the histones are loosened or the histone molecules are altered, the genes become available for expression. It is the complex activity g...ASBMB Schering-Plough Award lecture to focus on histone modifications in transcription
...ubiquitin to histone 2B. Normally in cells, DNA is wrapped around an octamer of histones. When the cell is ready to express the genes on the DNA, a variety of modifications are made to the histones, including the addition of ubiquitin. Through his research Dr. Strahl has discovered that Rad6 is associated w...Octopuses occasionally stroll around on two arms, UC Berkeley biologists report

...way that the DNA was packaged--some of the DNA was wrapped so tightly with proteins that it ceased to be accessible for transcription. This finding implicated a protein called silent information regulator 2 (SIR2), which is already known to play a role in gene silencing in yeast by modifying gene packaging. ...UCR chemist part of team identifying new areas of gene regulation
...with each other form a 'spool' around which DNA is wrapped in the cell. Grunstein, one of the scientists in the current team, discovered in 1991 that sites of histone acetylation, a modification of the protein, play a fundamental role in the regulation of gene activation and repression.
