| Research Abstract |
In order to understand how the stability of heterochromatin is ensured, we first produced a mutant which abolishes Lys9 methylation of histone H3 at 36℃. Analysis of this mutant indicated that the abolishment of heterochromatin requires cell cycle progression. Next, we performed a genetic screen and identified transcriptional regulators as factors that are responsible for the stability of heterochromatin. These results suggest that DNA replication and transcription are risk factors for heterochromatin instability.
