Melanie McDowell
Group Leader at MPI of Biophysics exploring ER membrane protein biogenesis
- The last chapter from my postdoc days is finally online! We solve structures of the ER membrane O-mannosyltransferase Pmt4 and uncover a functionally important cytosolic binding site for the Dol-P-Man substrate lipid - allosteric regulation or a long sought after Dol-P-Man flippase?? 🔄 rdcu.be/eUJfb
- Our first lab paper is out! We identify and solve the first structure of the SND3 translocon involved in fungal membrane protein insertion. Congratulations @tzujingyang.bsky.social, and our colleagues @saumyakm.bsky.social, @hummerlab.bsky.social and Julian Langer. Read more ⬇️ and ➡️ rdcu.be/eNgIO
- SNDing proteins into the membrane! Our new publication from @melaniemcdowell.bsky.social ’s group identifies the SND3 protein as a new route for membrane protein insertion! 🍄 📘 Read more here: www.mpg.de/25599408/102... Image: Louise Duever.

- The power of Chaetomium 🧫🏋♂️ super happy for the collaboration on this project! Congratulations to @ahmed-noor-agip.bsky.social, @pamornelas.bsky.social and all co-authors 🙌🏻

- Proud to share our first lab pre-print: “SND3 is the membrane insertase within a fungal multipass translocon” where @tzujingyang.bsky.social solved the structure of a ribosome-associated SND3-translocon complex involved in ER membrane protein insertion ➡️ doi.org/10.1101/2025...
- We reveal the cellular context of the SND3 component of the fungal SND pathway, showing it forms an intramembrane complex with CCDC47, the SEC61 translocon and TRAPɑ beneath the ribosome tunnel exit.
- Reposted by Melanie McDowellVery special feelings to announce this one... A project that started like 10 years ago is reaching the finish line, ready to shine. In a dream-team with @beckmannlab.bsky.social we solved the long-chased structure of the active membrane protein insertase SecYEG-YidC www.biorxiv.org/content/10.1...
