Excited to share our work on bacterial immune signaling! Our preprint reveals how RNA-guided Cas13 cleaves host tRNAs to generate small-molecule messengers that activate 2TMβ, linking RNA recognition to membrane damage and phage defense. 1/11

Mechanistic insights into chromatin modulation by the “orphan” remodeler ATRX
Duan et al. solved the structure of ATRX ATPase-nucleosome complex, uncovering three distinctive features that enable ATRX to remodel nucleosomes. These newly identified features are indispensable for protecting cells from G4 stress. The work provides a framework for interpreting both known and future mutations linked to ATRX-related disorders.

Some molecules, such as amino acids, exist as two variants that are each other’s mirror image. However, living organisms only contain one of these mirror images. How chemical asymmetry such as this could have emerged was long a mystery to chemists.
