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...

GenomicsDirect Recruitment of Polycomb Repressive Complex 1 (PRC1) to Chromatin by Core Binding Transcription Factors (ChIP-Seq)
Polycomb repressive complexes (PRCs) play key roles in developmental epigenetic regulation. Yet the mechanisms that target PRCs to specific loci in mammalian cells remain incompletely understood. In this study, we show that Bmi1, a core component of Polycomb Repressive Complex 1 (PRC1), binds direct...

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...

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...

TranscriptomicsGene silencing triggers Polycomb Repressive Complex 2 recruitment to CpG islands genome-wide [RNA-seq_differentiation]
Polycomb group (PcG) proteins are required for normal differentiation and development, and their activity is found deregulated in cancer. PcG proteins are involved in gene silencing, however, whether they initiate or maintain transcriptional repression is a subject of debate. Here, we show that knoc...

TranscriptomicsJarid2 regulates hematopoietic stem cell function by acting with Polycomb Repressive Complex 2
Polycomb Repressive Complex 2 (PRC2) has been shown to play a key role in hematopoietic stem and progenitor cell (HSPC) function. Analyses of mouse mutants harboring deletions of core components have implicated PRC2 in fine-tuning multiple pathways that instruct HSPC behavior, yet how PRC2 is target...

ProteomicsThe domesticated transposase ALP2 mediates formation of a novel Polycomb protein complex by direct interaction with MSI1, a core subunit of Polycomb Repressive Complex 2 (PRC2)
A large fraction of plant genomes is composed of transposable elements (TE), which provide a potential source of novel genes through “domestication” – the process whereby the proteins encoded by TE diverge in sequence, lose their ability to catalyse transposition and instead acquire novel functions ...
