Outline of Final Research Achievements

Combining robust and flexible feature of heterochromatin is one of most important characteristics of "Epigenetics". To give the both features to heterochromatin, the relationships between constitutive heterochromatin based on H3K9me3-HP1 (heterochromatin protein 1) and facultative heterochromatin based on H3K27me3-PRC2 (polycomb repressive complex 2) will be responsible for the mechanism. This study revealed that HP1 associates with PRC2 through a histone H3K9 methyltransferase. These molecular links will contribute to understand the mechanism for robustness and flexibility of heterochromatin.
