| Outline of Final Research Achievements |
To understand the molecular mechanism that establishes and maintains germline property, we analyzed chromatin modifiers in the nematode C. elegans. We found that the chromodomain protein MRG-1 acts as an interpreter of histone methylation and promotes histone acetylation, generating a unique histone modification pattern on the germline gene-specific loci. We also found that MRG-1 is involved in preventing transcription in premature primordial germ cells. In addition, we revealed an mRNA stability control that restricts maternally supplied chromatin modifiers in primordial germ cells.
