The euchromatic histone mark H3K36me3 preserves heterochromatin through sequestration of an acetyltransferase complex in fission yeast
January 3, 2020
This study reveals that the loss of heterochromatin silencing in Set2-deficient cells is due to unrestrained Mst2C activity, highlighting the need for spatially restricted chromatin-modifying enzymes to maintain distinct chromatin states.
Histone modifications as regulators of life and death in Saccharomyces cerevisiae
December 31, 2015
The mechanism by which chromosomes restructure during apoptosis is still poorly understood, but it is becoming increasingly clear that altered epigenetic histone modifications are fundamental parameters that influence the chromatin state and the nuclear rearrangements within apoptotic cells. This review highlights recent work on the epigenetic regulation of programmed cell death in budding yeast.
Time resolved DNA occupancy dynamics during the respiratory oscillation uncover a global reset point in the yeast growth program
September 1, 2014
Using multiple approaches, this work implies a nucleosome focusing event as a key step that resets transcription during the respiratory oscillation.
