Excited to start 2026 out with a new manuscript from our lab, please check out this thread from superstar postdoc @ryan_vignogna about how he discovered the function of a conserved secretory protein, and how this also led him to the identification of a new family of GAP proteins!
Mind the GAP 🚧🕳️🚧
Excited to share the latest preprint from the @Fromme_Lab showing that the DENN domain protein Avl9 functions as an Arf-GAP, revising long-standing assumptions about DENN protein function, 🧵:

Really proud of this paper just out in JCB. At almost every turn, SURF4 surprised us. Amazing PhD student, @jmaldutyte, sleuthed it out.

Columbia will award the 2024 Louisa Gross Horwitz Prize to Scott Emr and Wesley Sundquist for discovering the ESCRT pathway and revealing how it works.

Excited to announce an MBG faculty search for two assistant professor positions in collaboration with the Weill Institute for Cell and Molecular Biology, @weillinstitute.
Please share and apply!

New preprint. More on non-canonical motifs for DDR kinases.
Here we find that Tel1 (yeast ATM) targets D/E-S/T.
... more prevalent than S/T-Q
... NOT shared with Mec1.
May explain how Tel1 plays specialized roles in DNA repair and telomere maintenance.

Final version of our latest Kramer story is out! Congrats to @Hongyan_S for leading this effort & Adnan, Dylan, Alessandro, & @nicobuchon too! Read on to learn how Wnt signaling in surprisingly many cell types promotes stem cell proliferation in the gut: https://t.co/Z2OUo8jzAA
Check out the latest work from my lab, courtesy of soon-to-be Dr. @Biochem_Batman , who determined multiple #cryoEM structures of the human AP-3 adaptor complex. This was a years-long effort to reconstitute active Arf1-AP3 complexes on lipid nanodiscs https://t.co/JgQ3VOAGe3
Happy to share the newest preprint from @HollopeterLab@cornellvet: https://t.co/GCVafrHneu. We propose the Inversin complex works via a dimerization mechanism. You’re probably thinking, “What the $%@! is the Inversin complex?” Let me explain:
I'm so excited to finally share the results of my PhD work! Check out this thread for all of the highlights!
Ric1-Rgp1-Rab6 has been the most difficult #cryoEM project I've worked on so far, but I'm so happy with how it came together and what we learned about Rab6 activation!
Fittingly, the URL for the new AlphaFold3 server is:

#GolgiTime
*apparently it also works for proteins that do not localize to the Golgi, although we don't know why anyone would use it that way
Thrilled to announce AlphaFold 3 which can predict the structures and interactions of nearly all of life’s molecules with state-of-the-art accuracy including proteins, DNA and RNA. Biology is a complex dynamical system so modeling interactions is crucial https://t.co/Gs4GoOB3fD
We are excited to share a new preprint from the lab! Rab6 is a central regulator of the Golgi, important for trafficking and autophagy. @FeathersRyan used #cryoEM to determine the structural basis of the Rab6 activation process. (1/9)
