We show, in collaboration with Yifan Dai, that biomolecular condensates function as inherent catalysts. Interphase potentials give rise to electric fields at the interfaces of condensates that are tunable, strong enough to align substrates, & function as electro catalysts. doi.org/10.1016/j.mo...

RNA is more than genetic information: it can be a tool for cellular architects. In our new paper, we engineer RNA motifs to physically reorganize intracellular space in living mammalian cells. www.nature.com/articles/s41...
Congrats to our talented postdoc @amirbitran.bsky.social for his first preprint in the lab, a collaboration with the Bustamante lab, studying time-resolved protein folding during translation elongation with HDX-MS! Check out the attached manuscript and tutorial for more:

Finally out in @Cellcellpress! Proteins with long IDRs are prone to misfolding during protein synthesis. This is prevented by mRNA 3′UTRs that act as mRNA-based IDR chaperones. www.cell.com/cell/fulltex...
mRNA 3′ UTRs chaperone intrinsically disordered regions to control protein activity
Highly conserved mRNA 3′ UTRs act as co-translational chaperones for intrinsically disordered regions (IDRs), preventing inter-domain misfolding and enabling biogenesis of fully active proteins.

Thrilled to see our Deep-Phase paper now online in @cellcellpress.bsky.social! 🎉 The final version expands Deep-Phase across labeling modalities, adds dual-condensate imaging to dissect pathway specificity, and shows greater robustness to batch effects than classical image-analysis methods.

LLOMe has long been used to study lysosomal damage, yet how it works has remained a mystery. Using cryo-electron tomography, we show it forms amyloid structures inside lysosomes that mechanically rupture membranes – revealing a new paradigm for lysosomal failure. 🔗 doi.org/10.64898/202... #CryoET
Our new preprint! 🧬✨ www.biorxiv.org/cgi/content/... @ynagata.bsky.social et al. combined single-nucleosome imaging with Fucci probes to follow local chromatin behavior during interphase. Local nucleosome motion stays nearly constant from G1 to G2, except in early G1. Thanks to all coauthors!

I’m thrilled to share that my PhD work has been just published in Cell. After a long and bumpy ride, we uncovered the core function of nuclear speckles -splicing of GC-levelled exons- and traced the evolution of this gene architecture and condensates themselves to amniotes.
Our most recent work on the “function and evolution” of #nuclear-speckles is now online at Cell @cp-cell.bsky.social doi.org/10.1016/j.ce... Read the thread👇 for the highlights of our findings.
We are excited to share our new preprint which is now available to read on biorXiv: doi.org/10.64898/202... 🎉🎉🎉

Is euchromatin really “open”? Our new study @bioRxiv suggests otherwise. Using super-resolution imaging @shiori-iida.bsky.social @masaashimazoe.bsky.social reveals: Euchromatin forms condensed domains in live cells. Cohesin constrains them and prevents domain mixing. www.biorxiv.org/cgi/content/...
Our review on the physics of phase separation in cells has been published by Rep. Prog. Phys. 🎉 doi.org/10.1088/1361... We hope that the text and citations are helpful for anyone interested in physical descriptions of condensates in cells!
