GenomicsThe Histone Variant H2A.W Defines Heterochromatin and Promotes Chromatin Condensation in Arabidopsis
Histone variants play crucial roles in gene expression, genome integrity and chromosome segregation. However, to what extent histone variants control chromatin architecture remains largely unknown. Here, we show that the previously uncharacterized histone variant H2A.W plays a crucial role in conde...

TranscriptomicsWIP1 controls global heterochromatin silencing via ATM/BRCA1-dependent DNA methylation
WIP1 phosphatase is emerging as an important regulator of tumorigenesis, but no unifying mechanistic network has been proposed. Here we found that WIP1 plays a key role in the transcriptional regulation of heterochromatin-associated DNA sequences in germ-line and cancer cells. WIP1 was required for ...

GenomicsA transcription factor based mechanism for mouse heterochromatin formation
We identify Pax3 and Pax9 transcription factors (TFs) as important regulators of mouse heterochromatin. Simultaneous depletion of these factors results in loss of H3K9me3 from Major Satellite repeats and dramatic transcript overexpression. H3K9me3 enrichment at intergenic major satellite repeats is ...

ProteomicsMBD2 modulates heterochromatin architecture and composition
Heterochromatin (HC) is essential for nuclear integrity, genome stability, and gene regulation with pericentric heterochromatin (PCH) playing a key role. However, the mechanisms governing PCH compartmentalization remain poorly understood. Recent studies suggest that phase separation (PS) underlies t...

TranscriptomicsAn in vivo screen identifies compounds that disrupt heterochromatin integrity
Heterochromatin plays a key role in gene repression, maintaining genome integrity and chromosome segregation. Fission yeast, Schizosaccharomyces pombe, utilizes conserved components to direct heterochromatin formation using siRNA generated by RNA interference (RNAi) to guide a histone H3 lysine 9 me...

ProteomicsFission yeast Caprin protein is required for efficient heterochromatin establishment.
Heterochromatin is a key feature of eukaryotic genomes that serves important regulatory and structural roles in regions such as centromeres. In fission yeast, maintenance of existing heterochromatic domains relies on positive feedback loops involving histone methylation and non-coding RNAs. However,...

TranscriptomicsRNAi knock down of heterochromatin protein 1 in male and female Drosophila flies
Drosophila heterochromatin protein 1- HP1 is believed to be involved in active transcription, transcriptional gene silencing, and the formation of heterochromatin2-7. However, little is known about the function of HP1 during development. Using a Gal4-induced RNA interference system, we show that con...

TranscriptomicsTranscriptional gene silencing by Arabidopsis Microrchidia homologues involves the formation of heteromers
Epigenetic gene silencing is of central importance to maintain genome integrity and is mediated by an elaborate interplay between DNA methylation, histone posttranslational modifications and chromatin remodeling complexes. DNA methylation and repressive histone marks usually correlate with transcrip...

ProteomicsComplete loss of H3K9 methylation dissolves mouse heterochromatin organization
Histone H3 lysine 9 (H3K9) methylation is a central epigenetic modification that defines heterochromatin from unicellular to multicellular organisms. In mammalian cells, H3K9 methylation can be catalyzed by at least six distinct SET domain enzymes: Suv39h1/Suv39h2, Eset1/Eset2 and G9a/Glp. We used m...
