(Submitter supplied) The major function of Polycomb group proteins (PcG) is to maintain transcriptional repression to preserve cellular identity. This is exerted by two distinct repressive complexes, PRC1 and PRC2, that modify histones by depositing H2AK119ub1 and H3K27me3, respectively. Both complexes are essential for development and are deregulated in several types of human tumors. PRC1 and PRC2 exist in different variants and show a complex regulatory cross-talk. more...

(Submitter supplied) BAP1 is recurrently mutated or deleted in a large number of diverse cancer types, including mesothelioma, uveal melanoma and hepatocellular cholangiocarcinoma. BAP1 is the catalytic subunit of the Polycomb Repressive De-Ubiquitination complex (PR-DUB) which removes PRC1 mediated H2AK119ub1. We and others have shown that H2AK119ub1 is essential for maintaining transcriptional repression and contributes to PRC2 chromatin recruitment. more...

(Submitter supplied) The Polycomb repressive system is an essential chromatin-based regulator of gene expression. Despite being extensively studied, how it selects its target genes is poorly understood and whether its histone modifying activities are required for transcriptional repression remains controversial. Here, we directly test the requirement for PRC1 catalytic activity in Polycomb system function. To achieve this, we develop a new inducible mutation system in embryonic stem cells that completely removes PRC1 catalytic activity. more...

(Submitter supplied) Polycomb repressive complexes-1 and -2 (PRC1 and 2), silence developmental genes in spatiotemporally regulated manner during metazoan embryogenesis. How PcG proteins contribute to down-regulation of target genes upon differentiation, however, remains elusive. Here, by differentiating embryonic stem cells into embryoid bodies, we reveal a crucial role of a PCGF1 (Polycomb group RING finger protein 1)-containing variant PRC1 complex (PCGF1-PRC1) to facilitate induced down-regulation of a group of genes. more...

(Submitter supplied) ChIP-seq for H3K27me3 and Ring1B was performed in WT mESCs and mESCs containing catalytically inactive Ring1B (I53A mutant). Cells expressing catalytically inactive Ring1B maintain the spatial distribution of Ring1B and H3K27me3 but at reduced levels. These findings support the notion that PRC2 recruitment is, in part, dependent on H2A ubiquitination (H2AK119ub).

(Submitter supplied) Heritable gene silencing is essential for the development of multicellular organisms. Polycomb repressive complexes 1 and 2 (PRC1 and 2) catalyze and recognize histone H2A lysine 119 mono-ubiquitination (H2AK119ub1) and histone H3 lysine 27 trimethylation (H3K27me3), respectively, to mediate heritable gene silencing, but the mechanism of inheritance is not fully understood. Using an inducible gene silencing strategy, we show that the epigenetic inheritance of Polycomb silencing in human cells is strongly dependent on local DNA sequences and chromatin environment. more...

(Submitter supplied) Polycomb group (PcG) proteins are critical chromatin regulators for cell fate control. The mono-ubiquitylation on histone H2AK119 (H2AK119ub1) is one of the well-recognized mechanisms for Polycomb Repressive Complex 1 (PRC1)-mediated transcription repression. However, the specific H2AK119 deubiquitylation complex composed by ASX-like proteins (ASXLs) and BAP1 has also been genetically characterized as a Polycomb Repressive complex (PR-DUB). more...

(Submitter supplied) Polycomb Repressive Complexes (PRC), and their chromatin-modifying activities, are essential for the correct regulation of gene expression during cellular differentiation and development. Although their role in transcriptional repression is well described, a detailed molecular understanding of their complex assembly and enzymatic activity has been lacking. We therefore set out to characterize the relationship between PRC1 complex composition and its ability to catalyse H2AK119ub1 for one of the most abundant PRC1 complexes in embryonic stem cells, PCGF1-PRC1. more...
