Une marque épigénétique qui active pour mieux réprimer
Chez les eucaryotes, la marque épigénétique H3K27me3 est classiquement associée à la répression transcriptionnelle.

Excited to share our new preprint on BioRxiv! A collaborative effort spanning many years and several labs to uncover what the germline chromosomes of Paramecium really look like. 🔗 www.biorxiv.org/content/10.1... 1/5
Our latest publication is now out at Genome Biology! link.springer.com/article/10.1... We uncover a unique association between a H3K27me3 reader complex and active transcription. A thread with our key findings: (1/8) #TEsky #Polycomb #transcription #smallRNAs
