🔥 How does CTCF shape enhancer–promoter communication? In our new preprint, we systematically test how the position and orientation of CTCF binding sites (CBSs) influence gene regulation at the mouse Sox2 locus. 🧪 full paper can be found here: www.biorxiv.org/content/10.6...

1/ New preprint alert! In collaboration between the Rosen, Redding, Collepardo-Guevara & Gerlich labs, we uncover a surprising principle of chromosome organisation: electrostatic repulsion positions centromeres at the chromosome surface during mitosis. 🔗 doi.org/10.1101/2025...

🧵 CTCF is essential for embryonic development, but why has remained unclear. By combining gastruloids with a temporal degron system, we uncovered a surprising dual function — and it changes how we think about CTCF's role in development. 1/8 www.biorxiv.org/content/10.6...

During cell division, chromosomes reorganise into compact bodies in which centromeres localise precisely at the chromatin surface to enable kinetochore-microtubule interactions essential for genome se...

CTCF is an essential DNA binding protein whose absence leads to embryonic lethality. CTCF is primarily known for its role in 3D genome organization where its N-terminal domain interacts with cohesin to anchor chromatin loops. How CTCF facilitates proper embryonic development remains unclear, necessitating temporal control to resolve its stage-specific functions. By combining gastruloids, an in vitro model of embryonic development, with a degron system to rapidly deplete CTCF at defined timepoints, we show that early CTCF depletion impairs early gastruloid morphogenesis. Surprisingly, ATAC-seq and time-resolved RNA-seq revealed that differentiation was unaffected. CTCF binding is strongly enriched at promoters of downregulated genes. Re-expression of a CTCF variant with an N-terminal truncation, incapable of looping, was sufficient to rescue the expression of CTCF-promoter bound genes and the defects in morphogenesis. However, extended culture (up to 168 hours) of gastruloids reconstituted with N-terminal truncated CTCF led to their collapse. Our work shows that CTCF has a dual function in early mammalian development: at early stages CTCF regulates developmentally important genes through promoter binding, while at later stages its looping function is required for correct development. ### Competing Interest Statement The authors have declared no competing interest.

Please please please, if you are able, consider supporting Flybase fiscally. They need our help! I donated this evening. They are in danger of closing and any amount will help. We cannot allow this critical pillar of science to collapse!

FlyBase needs your help! We ask that European labs continue to contribute to Cambridge, UK FlyBase, whereas US and other non-European labs can contribute to US FlyBase. For more information and how to donate: wiki.flybase.org/wiki/FlyBase...
