Polycomb repressive complexes (PRCs) are important chromatin regulators of ES cell function. RYBP binds Polycomb H2A monoubiquitin ligases Ring1A and Ring1B, and has been suggested to participate in localizing Polycomb complexes to their targets. Moreover, constitutive inactivation of RYBP precludes...

We used microarrays to investigate a global change in gene expression by conditional depletion of Rybp in mouse ES cells. Total RNAs were extracted from wild-type and Rybp-deficient ES cells, and were subjected to microarray analysis using Affymetrix GeneChip Mouse Genome 430A 2.0 arrays

Rybp binding in wild-type, Eed-KO, and Dnmt1-KO ES cells ChIP on chip analysis was carried out using the Mouse Promoter ChIP-on-chip Microarray Set (G4490A, Agilent-014716 and Agilent-014717, Palo Alto, Calif., USA). ESCs were subjected to ChIP assay using a Rybp antibody (Santa Cruz; H-115). Purifi...

Gene expression change by Yaf2 KD in wild type or RYBP KO ES cells. Total RNAs were extracted from the respective ES cells, and were subjected to microarray analysis using Affymetrix GeneChip Mouse Genome 430A 2.0 arrays

The heterogeneous nature of mammalian PRC1 complexes has hindered our understanding of their biological functions. Here, we present a comprehensive proteomic and genomic analysis that uncovered six major groups of PRC1 complexes each containing a distinct PCGF subunit, a RING1A/B ubiquitin ligase, a...
