A new research article from the TI Lab.

In this article, we reveal the molecular mechanism by which a specific tubulin isotype renders cancer cells resistant to paclitaxel, a WHO-listed essential medicine for cancer treatment.

Excited to share our latest work on high-resolution comparative RNA knockdown profiles of shRNA, CasRx, and PspCas13b systems! biorxiv.org/content/10.1101/…

Very pleased that after a rigorous (and lengthy) review process, our paper visualizing how myosin generated forces modulate actin filament structure for mechanosensitive recogntion by α-catenin has appeared in @Nature

Very excited to share our latest preprint, where we visualize the impact of force on the catch bonding actin crosslinker α-actinin-4. Led by @alfredcchin, a great collaboration with Glen Hocky's lab.

Two weeks left to apply for a PhD with us at MRC-LMB in Cambridge. Join our team for an exciting project on transcription-coupled splicing to understand human gene regulation 🧬 Feel free to get in touch directly #PhD #cryoEM #biochemistry

The latest research article from the Ti Lab is finally out today in Nature Physics.

In this paper, by employing optical tweezers, cryo-EM, computer modeling, and single-molecule fluorescence microscopy, we found that tubulin isotypes can regulate how microtubules respond to forces,

We are delighted to announce that the 3rd DivIDE Conference will take place from 22–25 September 2025 with a fantastic lineup of speakers.
Registration opens soon - stay tuned and help us spread the word!
We are looking forward to meet many of you in Barcelona! ☀️

Excited that the peer-reviewed version of our fascin structure paper is now out in @NatureSMB. Thanks very much to the referees for their constructive feedback. rdcu.be/d6Tct
With help from @RuiZhangWUSTL we have successfully adopted Rui's protocol to achieve high-resolution cryo-EM 3D reconstruction of undecorated microtubules polymerized from recombinant tubulin. Please see the following user-friendly version of the workflow.

I want to take the opportunity to mention that I've written a slightly more user-friendly tutorial for the original microtubule seam-search protocol, together with other useful MT processing tricks.

The latest research article from Ti Lab. We employed cryo-EM structural analysis, single-particle fluorescence microscopy, and recombinant tubulin to reveal how tubulin acetyltransferases modify the K40 residue inside the microtubule lumen. (1/N)
processivity. Using recombinant tubulins that mimic preacetylated and postacetylated K40, we revealed the crosstalk between microtubule acetylation states and the cofactor acetyl-CoA in enzyme turnover. (3/N)
This work is a great collaboration with Dr. Yuanliang Zhai , @ChaoguZheng, and @XiangDavidLi1 at the University of Hong Kong. (4/4)
