Structural basis of asymmetric transcription through a composite nucleosome formed by a hexasome and an octasome

Zhihui Chen, Cheng-Han Ho, Hiroki Tanaka…·Hitoshi Kurumizaka

The paper investigates how RNA polymerase II transcribes through an OLDN, finding higher efficiency from the hexasome side and revealing conformational changes during transcription.

Structural basis for site-specific histone H3 acetylation-dependent regulation of RNAPII transcription through nucleosomes

Takumi Oishi, Suguru Hatazawa, Tomoya Kujirai…·Hitoshi Kurumizaka

The paper investigates how specific acetylation sites on histone H3 affect RNAPII transcription through nucleosomes using cryo-EM structures.

Structural basis of RNA polymerase II transcription on the H3-H4 octasome

Cheng-Han Ho, K. Nozawa, Masahiro Nishimura…·Hitoshi Kurumizaka

This study shows that RNA polymerase II transcribes the H3-H4 octasome more efficiently than the nucleosome, with distinct pausing patterns and stepwise tetramer disassembly.

Molecular and structural basis of the heterochromatin-specific chromatin remodeling activity by Arabidopsis DDM1

Akihisa Osakabe, Yoshimasa Takizawa, Naoki Horikoshi…·Hitoshi Kurumizaka

This study reveals how DDM1 remodels H2A.W nucleosomes in Arabidopsis, enabling chromatin writers to access heterochromatin for DNA methylation.
