Colliding ribosomes signal cellular stress LMU researchers uncover the mechanism by which ribosomes raise alarms in the cell.

📣Publication alert!
A team led by Roland Beckmann shows: Ribosome collisions activate the kinase ZAK and thus trigger the ribotoxic stress response — a key mechanism of the cellular stress defense. More about it here👇

We reveal cryo-EM structures of the MRN complex bound to DNA & TRF2 - showing how DNA breaks are sensed and regulated at telomeres.
Fantastic work by first authors @yilanfan.bsky.social @filizkuybu.bsky.social & Hengjun!

Recognition and remodelling of nucleosomes and hexasomes by the human INO80 complex The ATP-dependent INO80 chromatin remodeller slides and repositions nucleosomes to shape and maintain chromatin around gene regulatory elements and replication origins. Recent work uncovered capabilit...

Check out our pre-print on how the human INO80 complex acts on nucleosomes and hexasomes: PostDocs Priyanka & Manmohan et al. solved structures of INO80 bound to several substrates and completed missing questions about similarities of modes of actions across species🧬 www.biorxiv.org/content/10.1...

Structural basis for DNA double-strand break sensing by human MRE11-RAD50-NBS1 and its TRF2 complex The MRE11-RAD50-NBS1 (MRN) complex is a central, multifunctional factor in the detection, signaling and nucleolytic processing of DNA double-strand breaks (DSBs). To clarify how human MRN binds generi...

Happy to share our latest pre-print!
We solved the cryoEM structures of human DNA repair factor MRN bound to DNA and to TRF2. Main work of Yilan, Filiz @filizkuybu.bsky.social and Hengjun. Great collab within the @sfb1361.bsky.social and @genecenter-lmu.bsky.social 🧬🔨

Hello, Bluesky!
To kick things off here, we’re excited to share: The SLFN11 story continues! We combined cryo-EM and biochemical assays to explain how phosphorylation regulates SLFN11´s tRNA cleavage and ssDNA binding activities.
