Just celebrated 25 years of our lab with a BBQ and received a second "PhD" cap 🎓 What a journey it has been, great scientific successes, unforgettable colleagues and collaborations, ups and downs and everything in between. Here’s to 25 years of science and teamwork and the next scientific decade(s)

Excited to share our latest preprint! 🧬 Coiled coils are essential structural motifs in proteins but how do they move over time? Using high-speed AFM and MD simulations, we developed a quantitative framework to describe the dynamics of coiled coils in bacterial and human DNA repair complexes.

📣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👇 www.lmu.de/en/newsroom/...
