Check out our new work, led by talented @janhuemar.bsky.social, where we uncover that pioneer factor Oct4 remodels chromatin for DNA access not by opening it but by exploiting nucleosome breathing and forming clusters 🔥🔥🔥
🚨 🚨 🚨 New preprint alert!!! 🚨 🚨 🚨
In the past, we have learnt that Oct4 can induce nucleosome breathing on the mono-nucleosome level.
But what happens when you have a fibre of multiple nucleosomes?
