New direction of the Lab-mRNA lipid nanoparticles, led by the excellent postdoc, Jeehae Shin. Great collaboration with Cameron Douglas and Ciaran Seath. Ciaran Seath pubs.acs.org/doi/full/10.10…
Angiogenin controls angiogenesis (et plus) by nicking tRNAs. But it’s barely active alone. We discovered how 80S ribosome unlocks Ang’s active site and “brings in” tRNAs. Congrats to Anna Loveland and collab. w/Allan Jacobson! nature.com/articles/s4158…
Our preprint reporting the structure and mechanism of the natural product translation inhibitors paenilamicins is out…completely novel binding site on the ribosome! dlvr.it/T7CNnf…great collaboration with Suessmuth Lab Mankin_Vazquez_Lab
We want to thank the generous funding from European Research Council (ERC) and Novo Nordisk Foundation and that allowed us to complete this work Have a look at the follow-up twetorial by @proteofrankie explaining the findings #crispr #genomeediting #CryoEM #HorizonEU
Excited to share WD Hale's work out in NatureStructMolBiol: "Allosteric competition and inhibition in AMPA receptors" Through #cryoEM, Dylan outlines how allosteric inhibition occurs, and how this process prevents positive allosteric modulation during allosteric competition. Read for
To #TeamTomo ❄️🔬: Do you also sometimes see strange filaments in your #cryoET data and don’t know what they are? 🤔 Try #FilamentID! 🪄🤓 Check out our new paper at Cell by Jannik Hugener and Jingwei Xu together with the Matos lab cell.com/cell/fulltext/… 🧵(1/5)
Excited to share our newest publication on dual RNA-seq of human neutrophils and Neisseria gonorrhoeae, out today PLOS Pathogens! A true labor of love and testament to perseverance from Aimee Potter, PhD and awesome collaborator Hervé Tettelin and team Institute for Genome Sciences University of Maryland School of Medicine
In our new study we reveal how NAC coordinates and regulates successive co-translational nascent chain ⛓️ processing on the mammalian ribosome out today in nature rdcu.be/dRAQY collab with Deuerling Lab Shu-ou Shan Caltech Swiss National Science Foundation European Research Council (ERC) ETH Zurich
We are thrilled to share a truly exciting discovery by cryo electron tomography: the “hemifusome”- a new cellular organelle complex containing a hemifusion diaphragm! Tavakoli et al. biorxiv.org/content/10.110… Amirrasoul Tavakoli, shiqiong hu and @Becharakachar Tweetorial below (1/8)
1/8 ❄️🔬Excited to share our latest work published in Nature Communications! Led by Kaitlyn Abe and in colab with Tim Grant, we've discovered a simple, cost-effective way to mitigate sample damage at the air-water interface during grid preparation. #CryoEM rdcu.be/dSWfn
We find members of the TMC family of putative #mechanosensors at the tips of #intestinal #microvilli! Bechara Kachar Modeling Angela Ballesteros and molecular dynamics simulations Sotomayor Lab at OSU suggest they may be ion channels and/or lipid scramblases, like TMC1 at #stereocilia tips!
ncAAs can endow proteins with new activities, but their incorporation efficiencies during translation can be poor. Today in Nature Biotechnology, we report that altering mRNA codon usage can improve incorporation efficiency, yielding proteins with up to 3 ncAAs! nature.com/articles/s4158…
