CRISPR-Cas mediated DNA-interference typically relies on sequence-specific binding and nucleolytic degradation of foreign genetic material. Type IV-A CRISPR-Cas systems diverge from this general mechanism, using a nuclease-independent interference pathway to suppress gene expression for gene regulat...

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 recr...

Methanothermobacter thermautotrophicus is a model thermophilic hydrogenotrophic methanogen. The life and survival of M. thermautotrophicus is highly influenced by the availability of nutrients and temperature. To learn about adaptation mechanisms evolved by the archaea to cope with drastic temperatu...

This experiment was designed to determine the extent of gene misregulation in mESCs containing catalytically dead Ring1B in comparison to mESCs lacking Ring1B. Polyadenylated mRNA was prepared from wildtype mESCs (WT), mESCs deficient for Ring1B (KO) and mESCs cells containing catalytically dead Rin...

The goal of this study is to understand the genome-wide alterations in chromatin landscape induced by a histone mutation (H3.3K36M) derived from chondroblastomas Examination of genome-wide Ring1b distribution in cells expressing H3.3WT and H3.3K36M.

Native ChIP on chip for H3K27me3 in murine ES cells comparing WT and Ring1B-/- cells. Paper Abstract: How polycomb group proteins repress gene expression in vivo is not known. Whilst histone modifying activities of the polycomb repressive complexes have been studied extensively, in vitro data has su...
