Dynamic atlas of histone modi
WebCovalent modifications of the histone proteins have well-known roles in gene expression. Experiments reported during the past year have extended this paradigm to include roles for histone acetylation and phosphorylation in DNA double-strand break repair. In addition, new results now provide a definitive example of an acetylation histone code ... WebImportantly, large modified histone domains may represent the detectable output of a highly dynamic competition between methyltransferases and demethy-lases that continuously compete to either establish or remove specific histone marks.
