WebOct 14, 2024 · We found that both SAM and H3K27me3 are required for PRC2 binding to H3K27M in cells. Based on the requirement for EED to be occupied by an allosteric activator (i.e., H3K27me3 or JARID2) for EZH2 to tightly bind an H3K27M tail, we demonstrated that a H3K27M-H3K27me3 DN is a strong bivalent inhibitor of PRC2. WebFurther analysis revealed angioplasty-induced H3K27me3 peak redistribution to anti-proliferative genes from pro-proliferative genes, suggesting repression of the former and de-repression of the latter in keeping with the gene-repressing role of EZH2/H3K27me3.
