Research Abstract |
1. We discovered that GLP protein expression is posttranscriptionally regulated in murine embryonic male germ cells after sex determination and that low H3K9me2 level results from the absence of GLP (severe reduction of the G9a-GLP heteromeric complex). 2. We demonstrated that that H3K9 methyltransferase G9a/GLP complex suppresses transcription by independently inducing both H3K9 and DNA methylation. 3. We discovered that H3K9 methyltransferase ESET and ESET.mediated H3K9me3 play a crucial role in proviral silencing during the period early in embryogenesis when DNA methylation is dynamically reprogrammed.
