St. Jude scientists identified a direct role for PARP1 in chromatin remodeling, revealing for the first time how the protein partially disassembles nucleosomes to make damaged DNA accessible for repair. The findings could lead to more targeted PARP1 inhibitors and potentially reduce treatment toxicity. https://t.co/YWh6PuqrsW

Excited to share that our work is now published in Molecular Cell! We provide the first direct evidence for a role of hexasomes in DNA repair! Wonderful collaboration with @LabHalic, the Shelat labs, and St. Jude Imaging. https://t.co/TDbM38WDSJ

An advance in experimental throughput and sensitivity that revealed unexpected results!

[St. Jude Research @StJudeResearch]

Researchers have mapped 117 kinases capable of phosphorylating the RNA polymerase II tail, revealing modifications at previously disregarded positions beyond amino acids two and five. This discovery expands our understanding of gene transcription control. https://t.co/vuaoK6uxfD

[HalicLab @LabHalic]

We analyzed cryo-ET dataset EMPIAR-11830 (@AbhayKot) and achieved in situ nucleosome reconstruction at 6.7 Å resolution, revealing clear DNA and histone density. Many more cryo-ET findings from @LabHalic are on the way. #CryoET #TEAMTOMO.

[St. Jude Research @StJudeResearch]

Scientists used cryo-EM to capture 13 distinct structures of the chromatin remodeler SNF2H in action. This research provides a complete view of nucleosome sliding, a key process in gene regulation. https://t.co/PF5duXioK0

Our recent publication in Cell Research visualizes continuous motion of nucleosomal DNA by human chromatin remodeler SNF2H.

Over 20 years ago, the Eissenberg lab showed that phosphorylation of HP1 is important for its silencing function. Why? Key observations from our study in fission yeast:

Still hot off the press — @kellogg_liz and colleagues present the first structure of a Fanzor2!
Fanzors are eukaryotic RNA-guided DNA endonucleases. With the available Fanzor1 structures, the new work offers a comprehensive view of the family's evolution
