(Submitter supplied) Polycomb repressive complex-1 (PRC1) is essential for the epigenetic regulation of gene expression. SCML2 is a mammalian homolog of Drosophila SCM, a Polycomb-group protein that associates with PRC1. Here, we show that SCML2A, an SCML2 isoform tightly associated to chromatin, contributes to PRC1 localization and also directly enforces repression of certain Polycomb target genes. SCML2A binds to PRC1 via its SPM domain and interacts with ncRNAs through a novel RNA-binding region (RBR). 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...

(Submitter supplied) Xist lacking of XR-PID (B-repeat and part of C-repeat) can't recruit the polycomb during X chromsome inactivation. The majoring of Xist-mediated chromosomal silencing wouldn’t be achieved. We found that hnRNPK was the one of main contributors for binding B-repeat of Xist. When we tethered hnRNPK to Xist which lacks of XR-PID region, the silencing and polycomb recruitment are restored.

(Submitter supplied) The noncoding Xist RNA could mediate chromosome inaccessiblity, especially for the pre-open chromatin regions (enhancer, promoter, CTCF). However, Xist lacking the B-repeats loss the ability of closing the chromatin accessibility. ATAC-seq is consistent with the observation by ATAC-see. XR-PID denotes the Xist RNA polycomb interacting domain, including the entire B-repeats and part of C repeats.

(Submitter supplied) The Polycomb repressive complexes PRC1 and PRC2 play a key role in chromosome silencing by Xist RNA. Previously we have shown that initation of Polycomb recruitment is mediated by the PCGF3/5-PRC1 complex, which catalyses chromosome-wide H2A ubiquitylation (H2AK119u1), signalling recruitment of other PRC1 complexes, and PRC2. However, the molecular basis for PCGF3/5-PRC1 recruitment by Xist RNA remains unknown. more...

(Submitter supplied) 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 directly to the Runx1/CBFbeta transcription factor complex. Genome-wide studies in megakaryocytic cells demonstrate considerable chromatin occupancy overlap between the PRC1 core component Ring1b and Runx1/CBFbeta and functional regulation of a significant fraction of commonly bound genes. more...
