Hallmarks of multicellular eukaryotic genome organization are chromosome territories, compartments, and loop-extrusion-mediated structures, including TADs. However, these are mainly observed in model organisms, and most eukaryotes remain unexplored. Using Hi-C in the silkworm Bombyx mori we discover a novel chromatin folding structure, compartment S, which is “secluded” from the rest of the chromosome. This compartment exhibits loop extrusion features and a unique genetic and epigenetic landscape, and it localizes towards the periphery of chromosome territories. While euchromatin and heterochromatin display preferential compartmental contacts, S domains are remarkably devoid of contacts with other regions, including with other S domains. Polymer simulations show that this contact pattern can only be explained by high loop-extrusion activity within compartment S, combined with low extrusion elsewhere through the genome. This unique, targeted extrusion represents a novel phenomenon and underscores how evolutionarily conserved mechanisms—compartmentalization and loop extrusion—can be repurposed to create new 3D genome architectures. ### Competing Interest Statement The authors have declared no competing interest.

Transposable elements (TEs) comprise nearly half of the human genome. This Review discusses transcriptional and post-transcriptional mechanisms that repress TE activity, how TEs escape this suppressio...

Eukaryotes have linear DNA, and their telomeres are hotspots for transposons, which in some cases took over telomere maintenance. We identified several families of independently evolved telomeric tran...

Eukaryotic cells are highly structured and composed of multiple membrane-bound and membraneless organelles. Subcellular RNA localization is a critical regulator of RNA function, influencing various bi...
