The sonication-resistant heterochromatin (srHC) fragments of mESCs were isolated by sucrose gradient ultracentrifugation, and the heterochromatin-associated proteins were enriched by Co-IP combined with mass spectrometry (Co-IP/MS) using anti-H3K9me3, IgG was used as a negative control. The Nat10 in...
The cells were cotransfected with epitope-tagged expression plasmids or empty vector(EV) . Forty-eight hours after transfection, the cells were harvested with 500 μl of lysis buffer (20 mM Tris-HCl, pH=8.0; 100 mM NaCl; 0.5% NP-40; and 1 mM EDTA) supplemented with protease inhibitor cocktail (#04693...
In recent years, several chromatin-related proteins have been shown to regulate ESC pluripotency and/or differentiation, although the role of the major heterochromatin proteins in pluripotency remains largely unknown. Here we identify heterochromatin protein 1-beta (HP1β) to be differentially locali...
The KZFP/KAP1 (KRAB zinc finger proteins/KRAB-associated protein 1) system plays a central role in the silencing of transposable elements (TEs) and the maintenance of parent-of-origin DNA methylation at imprinting control regions (ICRs) during the wave of genome-wide reprogramming that precedes impl...
We examined the locations of Cbx3 by chromatin immunoprecipitation in ESCs and pre-iPSCs Examination of Cbx3 in mESC (mouse embryonic stem cells) and pre-iPSCs (fibroblast derived partially reprogrammed cells)
Individual retrotransposon integrants are differentially controlled by KZFP/KAP1-dependent histone methylation, DNA methylation and TET-mediated hydroxymethylation in naïve embryonic stem cells
