Transcription profiling of mouse embryonic fibroblasts from Bmi1 knock-outs as compared to wild-type.

ABSTRACT: Polycomb group (PcG) proteins control organism development by regulating the expression of developmental genes. Transcriptional regulation by PcG proteins is achieved at least partly through the PRC2-mediated methylation on lysine 27 of histone H3 (H3K27) and PRC1-mediated ubiquitylation on lysine 119 of histone H2A (uH2A). As an integral component of PRC1, Bmi1 has been demonstrated to be critical for H2A ubiquitylation. Although recent studies have revealed the genome wide binding patterns of some of the PRC1 and PRC2 components, as well as the H3K27me3 mark, there have been no reports describing genome wide localization of uH2A. Using the recently developed ChIP-Seq technology, here we report genome wide localization of the Bmi1-dependent uH2A mark in MEF cells. Gene promoter averaging
