GenomicsJarid2 and PRC2, Partner in Regulating Gene Expression
The Polycomb Group proteins foster gene repression profiles required for proper development and unimpaired adulthood, and comprise the components of the PRC2 complex including the histone H3 lysine 27 (H3K27) methyltransferase Ezh2. How mammalian PRC2 accesses chromatin is unclear. We find that Jari...

ProteomicsDynamic protein interactions of the Polycomb Repressive Complex 2
Polycomb proteins assemble to form complexes with important roles in epigenetic regulation. The Polycomb Repressive Complex 2 (PRC2) modulates the di- and tri-methylation of lysine 27 on histone H3, each of which are associated with gene repression. Although three subunits, EZH1/2, SUZ12 and EED, fo...

GenomicsChIP-seq for PRC2 components and H3K27me3 in E14 mouse embryonic stem cells
This experiment sought to determine the chromatin structure and PRC2 occupancy at the promoters of all genes in mouse ESCs ChIP-seq for EZH2, SUZ12, and H3K27me3 were performed on WT E14 cells in 2 biological replicates each. In addition H3K27me3 ChIP-seq was also performed on a clone of E14 cells e...

GenomicsFunctional analysis of AEBP2, a PRC2 Polycomb protein, reveals a Trithorax phenotype in embryonic development and in ES cells
The Polycomb repressive complexes PRC1 and PRC2 are key mediators of heritable gene silencing in multicellular organisms. Here we characterize AEBP2, a known PRC2 cofactor which, in vitro, has been shown to stimulate PRC2 activity. We show that AEBP2 localises specifically to PRC2 target loci, incl...

GenomicsPolycomb PHF19 binds H3K36me3 and recruits PRC2 and demethylase NO66 to embryonic stem cell genes during differentiation
The Polycomb group proteins are repressive chromatin modifiers with essential roles in metazoan development, cellular differentiation and cell fate maintenance. How Polycomb proteins access active chromatin in order to confer transcriptional silencing during lineage transitions remains unclear. Here...

GenomicsDeletion of RING1A/B and loss of H2AK119ub1 affects PRC2 occupancy and H3K27me3 genome-wide
The chromatin modifying activities inherent to polycomb repressive complexes PRC1 and PRC2 play an essential role in gene regulation, cellular differentiation, and development. However, the mechanisms by which these complexes recognize their target sites and function together to form repressive chro...

GenomicsPRC2 loss amplifies Ras-driven transcription and confers sensitivity to BRD4-based therapies [ChIP-seq]
The polycomb repressive complex 2 (PRC2) exerts oncogenic effects in many tumour types1. However, loss-of-function mutations in PRC2 components occur in a subset of haematopoietic malignancies, suggesting that this complex plays a dichotomous and poorly understood role in cancer2,3. Here we provide ...

GenomicsChIP-seq analysis of PRC2 core subunits in primary human erythroid progenitor cells
Polycomb Repressive Complex 2 (PRC2) plays crucial roles in transcriptional regulation and stem cell development. However, the context-specific functions associated with alternative subunits remain largely unexplored. Here we show that the related enzymatic subunits EZH1 and EZH2 undergo an expressi...

TranscriptomicsHira-dependent histone H3.3 deposition facilitates PRC2 recruitment at developmental loci in ES cells [CATCH-IT]
Polycomb repressive complex 2 (PRC2) regulates gene expression during lineage specification through trimethylation of lysine 27 on histone H3 (H3K27me3). In Drosophila, polycomb binding sites are dynamic chromatin regions coupled to incorporation of the histone variant H3.3. Here we show in mouse em...
