Histone dynamics within the nucleosome play a critical role in SNF2h-mediated nucleosome sliding

N. Gamarra, G. Narlikar

The paper replicates and confirms that histone core dynamics are essential for SNF2h-mediated nucleosome sliding, highlighting the importance of proper experimental design in studying nucleosome dynamics.

Electron cryo-microscopy structures of remodeler-nucleosome intermediates suggest allosteric control through the nucleosome.

J.-P. Armache, N. Gamarra, S. L. Johnson, J. D. Leonard, S. Wu, G. J. Narlikar, Y. Cheng

The paper presents cryo-EM structures of SNF2h-nucleosome complexes with ADP-BeFx, revealing conformational states that suggest allosteric control through the nucleosome.

Organization and Regulation of Chromatin by Liquid-Liquid Phase Separation

B. A. Gibson, L. K. Doolittle, L. E. Jensen, N. Gamarra, S. Redding, M. K. Rosen

This study shows that chromatin undergoes liquid-liquid phase separation under physiological conditions, driven by histone tail interactions and modulated by acetylation and H1, leading to genome compaction and organization.
