Structural basis of herpesvirus helicase-primase inhibition by pritelivir and amenamevir Structural studies of HSV-1 helicase-primase revealed how pritelivir and amenamevir bind and block its helicase activity.

New work from Tahirov x Lim collaboration! @qixianghe.bsky.social from my lab contributed the cryo-EM structures for this work. We are excited to help explain how anti-HSV drugs work and to guide their future development.

Excited to share our latest @nature.com: How does naloxone (Narcan) stop an opioid overdose? We determined the first GDP-bound μ-opioid receptor–G protein structures and found naloxone traps a novel "latent” state, preventing GDP release and G protein activation.💊🧪 🧵👇 www.nature.com/articles/s41...

I love AlphaFold—but please include PAE (Predicted Aligned Error) plots for every “interaction.” Pretty PDBs ≠ proof. If the PAE doesn’t show an interface, it ain’t one. Show the plots. Structural biology's reputation is on the line.

We have a new preprint for you. Naked mole rats are very long-lived rodents and have increased translational fidelity.

Interestingly, 28S ribosomal RNA is split. Here we investigated the structure of the ribosome by single particle cryo-EM. Take a look.

Cardiolipin dynamics promote membrane remodeling by mitochondrial OPA1 - Nature Communications This study reveals how cardiolipin governs mitochondrial morphology by modulating the activity of human OPA1 and how its replacement by monolyso-cardiolipin, as observed in Barth syndrome, impacts mitochondrial membrane-shaping mechanisms.

Excited to share that our paper on mitochondrial cardiolipin dynamics is published in @natcomms.nature.com today! We provide molecular explanations for unique aspects of mitochondrial morphology and the mechanisms underlying cardiolipin-related Barth Syndrome.

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.

National Institutes of Health v. American Public Health Association When political ideologies interfere with science, everyone loses.

Right now, the continuation of many restored NIH grants relies on the SCOTUS shadow docket. SCOTUS is not immune to pressure.
Also, if you are represented by one of the 14 R senators that called for the restoration of NIH grants, please write them a thank you. Good behavior should be rewarded.
