JARID2 forms a stable complex with PRC2 (containing EZH2, SUZ12, EED) in ES cells, is required for PRC2 binding to >90% of PcG target genes genome-wide, and is sufficient to recruit PcG proteins to a heterologous promoter; inhibition of JARID2 causes major loss of PRC2 binding and reduction of H3K27me3 at target genes. |

JARID2 is methylated by PRC2 (EZH2); this methylation is recognized by the EED subunit of PRC2 and triggers allosteric activation of PRC2 enzymatic activity. Jarid2 methylation promotes PRC2 activity at loci devoid of H3K27me3 and is required for correct H3K27me3 deposition during cell differentiation. |

Jarid2 is an important mediator of Xist-induced PRC2 targeting to the inactive X chromosome during X-chromosome inactivation. The B and F repeats of Xist RNA are critical for Jarid2 recruitment via its unique N-terminal domain; Xist-induced Jarid2 recruitment occurs chromosome-wide independently of functional PRC2, and Jarid2 loss prevents efficient PRC2 and H3K27me3 enrichment on Xist-coated chromatin. |

Inactivation of both G9a and GLP (but not G9a alone) abolishes Jmj-mediated H3-K9 methylation and cyclin D1 repression. |
