TransitID is out today in Cell! This is a proximity labeling method for unbiased discovery of endogenous proteins that traffick from a defined “source” location to a defined “destination” location. TransitID uses sequential labeling by TurboID in the source, followed by a chase

- I was taken by surprise this morning when congratulatory emails started arriving in my inbox. I'm incredibly honored, grateful, and humbled to be included among such an esteemed group of scientists, many of whom I’ve admired for decades. While this recognition is individual,
- We wrote a proximity labeling (PL) review to highlight all the exciting applications of PL to protein-protein & protein-RNA/DNA interaction mapping. See examples of PL applied to enzyme-substrate interactions, insoluble baits, dynamic PPI networks & multifunctional proteins.
- 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 transgene expression and real-time
- Can we perform unbiased discovery of endogenous proteins that traffick from one organelle to another in living cells? Learn about our new proximity labeling method, TransitID, here: Full video of ASCB lecture at tinyurl.com/3dste3am
00:00 - Huimin Zhao shared this hilarious 1998 abstract on the “Directed Evolution of a Full Professor” at the #LSIsymposium2019. “A pool of grad student clones was [selected] on minimal money media & the ability to work long hours w/vending machine snacks as a sole carbon source.”
- Deeply saddened by the passing of Lubert Stryer, father of FRET, pioneer of DNA and peptide microarrays, author of the famous Biochemistry textbook used across the world. Many may not know that he was also an extremely generous supporter of the arts and deeply passionate about
- Light-regulated TurboID, or LOV-Turbo, is a feat of engineered allostery, created by @SongyiLee10 and @CheahJoleen via structure-guided design, then optimized by yeast display directed evolution. Activity is nearly undetectable in the dark state, but biorxiv.org/cgi/content/sh…
- APEX peroxidase is a versatile tool for proximity labeling and electron microscopy (EM) but its requirement for toxic H2O2 is a liability. We now report LaccID, a multicopper oxidase evolved from an ancestral fungal laccase that oxidizes aromatic substrates using non-toxic O2
- First time giving a talk in a baseball stadium, with slides displayed on a jumbotron! At the Stanford Genetics retreat, where organizers have been creative & working hard to put on a safe in-person event *Retreat swag included baseball Tshirts and double helix baseball caps!
- LOV-Turbo is published today in @naturemethods and plasmids for LOV-Turbo are available on Addgene, here: addgene.org/browse/article… We hope many people will use LOV-Turbo in exciting new ways! nature.com/articles/s4159… If you plan to use NanoLuc BRET to activate LOV-Turbo, pleaseLight-regulated TurboID, or LOV-Turbo, is a feat of engineered allostery, created by @SongyiLee10 and @CheahJoleen via structure-guided design, then optimized by yeast display directed evolution.

- We’ve written a detailed step-by-step protocol for how to use TurboID (& split-TurboID) in cultured mammalian cells! How to select your proximity labeling (PL) enzyme, design & execute PL experiments, & analyze the resulting mass spec data. tinyurl.com/y2rrftu6
- To improve spatial and temporal control over proximity labeling, we’ve developed LOV-Turbo, a reversible & blue-light activated variant of TurboID. Almost no dark state leak & +light activity comparable to miniTurbo. We are doing pulse-chase labeling with LOV-Turbo to map..
- In my several decades in science, few moments have been as seismic as when AlphaFold burst onto the scene (seeing the first structure of a K+ ion channel, from Rod MacKinnon, was up there too). We rushed to fold every protein we had been working on, that had no structure, and
