How do chromatin remodelers use #IDRs to find TF binding partners? In our new Molecular Cell paper, we show that Ξ²-catenin is an adaptor that links SWI/SNF (cBAF) subunit ARID1A with binding partners via IDR-domain interactions.

Unique territorial and compartmental organization of chromosomes in the holocentric silkworm 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 β€œsecluded” 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 mechanismsβ€”compartmentalization and loop extrusionβ€”can be repurposed to create new 3D genome architectures. ### Competing Interest Statement The authors have declared no competing interest.

A little belated posting, but we (Emily Navarrete, Leonid Mirny, me) have an updated preprint in collaboration the Ines Drinnenberg, HΓ©loΓ―se Muller, JosΓ© Gil Jr, + others on the strange and striking compartmentalization of silkworm chromatin: www.biorxiv.org/content/10.1...
