That’s a wrap on this year’s Chromatin Consortium in Woods Hole! 🧬 The @danielgerlich.bsky.social , @rcollepardo.bsky.social , @vram142.bsky.social, Gibson, and Rosen labs came together to exchange ideas, run experiments, and explore chromatin organisation from different angles. 1/4

Check out our latest work in collaboration with @kazu-maeshima.bsky.social and @masaashimazoe.bsky.social We show that H1 is a dynamic, multivalent “liquid-like” glue of chromatin in cells: it bridges multiple nucleosomes & exchanges partners frequently to enable both compaction and flexibility

How do DNA sequence and histone composition modulate nucleosome plasticity? We investigated this by comparing the behaviour of 40 chemically different nucleosomes. Check our preprint below.

Is chromatin ordered or disordered? It all depends on the linker DNA length. Check our latest work with Mike Rosen and Sy Redding. We explore how changes in linker DNA length (as small as 1 bp) fine-tune chromatin structure, between order and disorder, and the properties of chromatin droplets
