(Part 1/2) Excited to share our recent work with Prof. Nicolas Fawzi’s group (nicolasluxfawzi.bsky.social), now out in Angewandte Chemie (onlinelibrary.wiley.com/doi/full/10....)! We show how RNA reshapes FUS condensate assembly and dynamics. Congrats to Tongyin, Kandarp, Samara, Qizan, Priyesh!

(Part 2/2) Using NMR and all-atom MD, we show that methionine oxidation disrupts both helical self-association and long-range transient contacts in the TDP-43 LC domain, both of which are important for its phase separation.

(1/10) How do diverse leukemia mutations converge on the same molecular program? In #RibackLab first manuscript @cp-cell.bsky.social, collaboration with @goodell-lab.bsky.social shows that disparate mutations rewire shared protein networks to form nuclear condensates called C-bodies.

I get emails from people I do not know and wonder "Was this written by AI?" Given this, will we start ignoring emails more than we already do and place more value on face-to-face and phone conversation (I guess you could get an AI voice to have a conversation for you!), going back in time?

On the cover of issue 10: 1,6-hexanediol scrutiny by @nicolasluxfawzi.bsky.social et al Interferon-induced ADP-ribosylation by PARP14 Nuclear envelope-associated lipid droplets & inflammation Ancient cyanobacterial proto-circadian clock system reconstruction ... www.embopress.org/toc/14602075...
This cover highlights the article Molecular insights into the effect of 1,6-hexanediol on FUS phase separation by Tongyin Zheng, Noah Wake, Shuo-Lin Weng, Theodora Myrto Perdikari, Anastasia C. Murthy, Jeetain Mittal, and Nicolas L. Fawzi. 1,6-hexanediol disrupts many phase-separated condensates in cellula and in vitro much better than other similar alkanediols. Biophysical and biochemical experiments probe how 1,6-hexanediol decreases phase separation of the RNA-binding protein FUS through hydrophobic disruption and show why similar alkanediols have less potency. Conversely, 1,6-hexanediol does not disrupt charge-mediated condensates. The image represents contacts that 1,6-hexanediol (red mesh) forms with disordered domains of FUS (orange tubes) that discourage FUS-FUS interactions and phase separation into condensates (background).
