Repressive and non-repressive chromatin at native telomeres in
Epigenetics & Chromatin, 2009 Background In Saccharomyces cerevisiae genes that are located close to a telomere can become transcriptionally repressed by an epigenetic process known as telomere position effect.

Identification of polycomb repressive complex 1 and 2 core components in hexaploid bread wheat
BMC Plant Biology, 2020 Background Polycomb repressive complexes 1 and 2 play important roles in epigenetic gene regulation by posttranslationally modifying specific histone residues. Polycomb repressive complex 2 is responsible for the trimethylation of lysine 27 on histone H3;

Combinations of maternal-specific repressive epigenetic marks in the endosperm control seed dormancy
eLife, 2021 Polycomb Repressive Complex 2 (PRC2)-mediated trimethylation of histone H3 on lysine 27 (H3K27me3) and methylation of histone 3 on lysine 9 (H3K9me) are two repressive epigenetic modifications that are typically localized in distinct regions of the ...

Trithorax group proteins: switching genes on and keeping them active [PDF]
, 2011 Cellular memory is provided by two counteracting groups of chromatin proteins termed Trithorax group (TrxG) and Polycomb group (PcG) proteins. TrxG proteins activate transcription and are perhaps best known because of the involvement of the TrxG protein ...
