🧬 Our “Behind the Paper” is now online at Nature Communities:
“Active chromatin is not simply open—it forms compact domains that cohesin keeps from mixing.”
📖 A short story behind our recent @natgenet.nature.com paper.

This is so beautiful! CTCF got such a creative way to organise chromatin!
🧪🧬New preprint We present cryo-EM structures of reconstituted CTCF–nucleosome complexes, showing CTCF dimerization drives nucleosome oligomerization into defined higher-order assemblies. Disrupting CTCF–CTCF interfaces in mESCs reduces looping and impairs differentiation. tinyurl.com/CTCF-nucleos...

Unicore identifies single-copy protein structures across genomes using Foldseek, bypassing slow structure predictions by utilizing 3Di predictions from ProstT5, enabling rapid phylogenetic inference at the tree-of-life scale. 1/n
