This one is a bit of a departure from the usual and definitely a work in progress! We found that by using ab initio reconstruction at very high res, in very small steps, we could crack some small structures that had eluded us - e.g. 39kDa iPKAc (EMPIAR-10252), below. Read on for details... 1/x
High-resolution ab initio reconstruction enables cryo-EM structure determination of small particles https://www.biorxiv.org/content/10.1101/2025.09.08.674935v1
Finally in @nature.com 🎉 We uncovered step-wise mTORC1 activation on membrane: RAG–Ragulator recruits, RHEB pushes closer, and direct membrane contacts by RAPTOR + mTOR trigger full kinase activity.👉 The membrane is not just a platform — it’s part of the mechanism. www.nature.com/articles/s41...

Extremely excited to share that I’m joining Columbia University @columbiauniversity.bsky.social as an Assistant Professor! We will explore how the mobile genome works—how transposons shape us, our DNA and how they can be harnessed to build useful technologies. #NewPI #RNAsky #TEsky thawanilab.org

Excited to see work led by @autophazeke.bsky.social, @minghaochen.bsky.social, Thanh Nguyen, and Ainara Claveras out in @science.org today, the culmination of a 15-year project to understand structurally how the synthesis of the critical lipid of autophagy, PI3P, is regulated. tinyurl.com/ywvjh8u4

Our new FASEBJ paper. We looked into mTOR Ser1261 phosphorylation in human and mouse muscle, proposed by Diane Fingar's lab to be first an Akt and then AMPK site regulating mTORC1 and 2 activity. Clearly AMPK site but impact on mTORC unclear in our hands faseb.onlinelibrary.wiley.com/doi/10.1096/...

Scientific Director, Cal-Cryo. We are looking for an outstanding microscopist to run our cryo-EM facility (two Krioses and an Arctica), increase training, engagement, and collaboration on campus, expand our user base, and join our community of cutting edge cryo-EM researchers. tinyurl.com/ykasna3p

Every year, I give my lab (and myself) a "mini-sabbatical" to pursue creative endeavors outside of regular work/studies. So I spent some time reflecting on my thoughts on #AI + the role of professors in this AI transformation via a short film 📽️: www.youtube.com/watch?v=6MPs... #AcademicSky

So excited to share our work developing a new class of modular synthetic GPCRs, out today @Nature! Check it out nature.com/articles/s41...
Could one envision a synthetic receptor technology that is fully programmable, able to detect diverse extracellular antigens – both soluble and cell-attached – and convert that recognition into a wide range of intracellular responses, from gene expression and real-time fluorescence to modulation..

How to write a grant? 1. The application is for the reviewer, not you, the applicant. 2. Communicate in stories. 3. Make your story cohesive—leave no puzzling gaps. 4. Make your story resonate to keep the reviewer reading. 5. Accept chance and noise in peer-review. www.pnas.org/doi/epub/10....

First post on bluesky gotta be the structure of mTORC1 on membrane! A great collaboration and interesting frontier for SPA cryoEM!
Proud of new work tinyurl.com/yhz4c6ry from the lab by Zhicheng (Chen) Cui using single-particle cryo-EM on liposomes to show how mTORC1 integrates nutrient and growth factor signaling at lysosomes, collab. w/ G. Napolitano,A. Esposito, and A. Ballabio.
You are up to date.
