Epigenetic gene silencing by heterochromatin primes fungal resistance [PDF]
, 2021 Genes embedded in H3 lysine 9 methylation (H3K9me)–dependent heterochromatin are transcriptionally silenced. In fission yeast, Schizosaccharomyces pombe, H3K9me-mediated heterochromatin can be transmitted through cell division provided the ...

De Novo Polycomb Recruitment: Lessons from Latent Herpesviruses
Viruses, 2021 The Human Herpesviruses persist in the form of a latent infection in specialized cell types. During latency, the herpesvirus genomes associate with cellular histone proteins and the viral lytic genes assemble into transcriptionally repressive ...

Candida albicans repetitive elements display epigenetic diversity and plasticity [PDF]
, 2016 Transcriptionally silent heterochromatin is associated with repetitive DNA. It is poorly understood whether and how heterochromatin differs between different organisms and whether its structure can be remodelled in response to environmental signals. Here,

PLoS Genetics, 2019 H3K9 methylation (H3K9me) is a conserved marker of heterochromatin, a transcriptionally silent chromatin structure. Knowledge of the mechanisms for regulating heterochromatin distribution is limited.

Mediator directs co-transcriptional heterochromatin assembly by RNA interference-dependent and -independent pathways. [PDF]
PLoS Genetics, 2013 Heterochromatin at the pericentromeric repeats in fission yeast is assembled and spread by an RNAi-dependent mechanism, which is coupled with the transcription of non-coding RNA from the repeats by RNA polymerase II. In addition, Rrp6, a component of the

Histone crosstalk directed by H2B ubiquitination is required for chromatin boundary integrity [PDF]
, 2011 Genomic maps of chromatin modifications have provided evidence for the partitioning of genomes into domains of distinct chromatin states, which assist coordinated gene regulation.

Sex Differences in Drosophila melanogaster Heterochromatin Are Regulated by Non-Sex Specific Factors. [PDF]
PLoS ONE, 2015 The eukaryotic genome is assembled into distinct types of chromatin. Gene-rich euchromatin has active chromatin marks, while heterochromatin is gene-poor and enriched for silencing marks.

Ccq1–Raf2 interaction mediates CLRC recruitment to establish heterochromatin at telomeres
Life Science Alliance, 2021 This study unveils a role of Ccq1–Raf2 interaction in CLRC recruitment to establish heterochromatin at telomeres, providing a positive feedback mechanism between shelterin and CLRC for subtelomeric heterochromatin assembly.

Nature Communications, 2021 The heterochromatin compartment is key for genome stability and cell fate transitions. Here, by tracking the heterochromatin response to UV damage in real time, the authors reveal how heterochromatin features are preserved following a genotoxic stress ...
