New and HOT in Chemical Science! 🔥 "Inhibitor fluorination pattern modulates protein surface dynamics and chemically induced dimerization" by Ute A. Hellmich and colleagues. Read for free: doi.org/10.1039/d6sc...
Schematic illustration of a molecular glue strategy targeting the Trypanosoma brucei redox protein Tpx. At the top, a trypanosome parasite is linked to a zoomed-in view of the Tpx redox cascade and a small-molecule glue structure. Three panels compare ligand-binding poses within a Tpx pocket containing a tryptophan (Trp) residue. Left: a detached ligand pose (green) fails to engage Trp, producing a weak molecular glue effect and low Tpx dimer affinity. Centre: a dynamic ligand pose (gold) shows transient interactions and intermediate glue strength. Right: an attached ligand pose (purple) forms stable interactions with Trp, generating a strong molecular glue effect and high Tpx dimer affinity. An arrow along the bottom indicates increasing chemically induced Tpx dimer affinity from left to right.

AMPA receptor gating proceeds through an intermediate pre-active state that has structurally remained an enigma. We used cryo-EM as well as full and partial agonists to resolve this state and for the first time structurally reveal the complete gating pathway of AMPARs. www.nature.com/articles/s41...

🚨🧠🔬 Dopamine was discovered over a century ago, and has long been thought to only signal through metabotropic means. In our new preprint, we provide evidence that dopamine can directly signal through the "orphan" GluD ionotropic receptors. More to come! #iGluRs #neuroscience #dopamine #cryoEM

Where does anti-NMDAR autoimmune encephalitis come from? Our new work suggests that ectopic NMDAR expression in tumors can trigger anti-cancer immunity, and the resulting antibodies may drive encephalitis-like symptoms. A dynamic Janowitz-Furukawa lab collaboration. www.nature.com/articles/s41...

Calcium and magnesium in the pore of NMDA receptors! Lipids play an unexpected role. The hydration shells of Ca2+ and Mg2+ could be the difference between permeation and block. So much physiology in the energetics of H2O. Very stimulating work! Congrats @lab-furukawa.bsky.social #iglurs
