  4. β-arrestins regulate #GPCR signaling & trafficking, adopting multiple conformational states with different outcomes. This study shows how receptor CXCR7 induces stepwise conformational changes in β- #arrestin 2, uncovering an arginine switch mechanism of activation @PLOSBiology plos.io/3UfTd71

  5. Check our new preprint !
    Triple orthogonal labeling with 2 unnatural aminoacids + 1 SNAP-Tag for 3 color #smFRET.
    We resolve a new intermediate in the activation of metabotropic glutamate receptor 2.

  9. The version of record of our #Nematostella #GPCR #neuropeptide paper has now been published
    elifesciences.org/articles/906

    For #cnidarian #neuroscience there are lots of new deorphanised receptors described in the paper. We also identified orthologs across cnidarian species, including corals, #Exaiptasia etc. so the resource is not limited to Nematostella.

  10. New study shows that the C-terminal fragment of the #GPCR #muscarinicM2receptor, translated from an #IRES, localizes to the #mitochondrial inner membrane & is upregulated upon stress exposure, reducing respiration & #ROS to protect cells #PLOSBiology plos.io/3Uomtb8

  11. #BC007 ist ein potenzieller Wirkstoffkandidat gegen das #PostCovidSyndrom und andere #Autoimmunkrankheiten mit funktionellen Autoantikörpern gegen #GProtein gekoppelte Rezeptoren #gpcr Es handelt sich um ein #aptamer das diese krankmachenden #Autoantikörper blockieren soll. Die klinische Phase-II-Studie reCOVer der Augenklinik des #Uniklinikums #Erlangen untersucht den molekularen Weg bestimmter Autoantikörper beim Post-COVID-Syndrom.

  12. The #GPCR CMKLR1 responds to the #adipokine #chemerin and is abundant in #InnateImmune cells. Structure of CMKLR1 in complex with #Gprotein and a peptide agonist (+ mutagenesis & simulations) reveals mechanisms of action #PLOSBiology plos.io/4a6Igvd

  13. First preprint about my work at Schrödinger:

    We show how to predict ligand efficacy via absolute binding free energy perturbation on different receptor conformations — confirming and utilizing the principle that the functional response of a receptor is mainly determined by the thermodynamics of ligand binding.

  14. Our favourite #Platynereis #opsin now in the mammalian brain as a new #optogenetic tool!

    "Here we ... found that the Platynereis dumerilii ciliary opsin ... is an efficient, versatile, light-activated bistable GPCR that can suppress synaptic transmission in mammalian neurons with high temporal precision in-vivo "

  15. Previously, only one #GPCR with a ligand was known in #cnidaria, the receptor for the #Clytia Maturation-Inducing-Hormone. This receptor was found by Gonzalo Quiroga Artigas and Philipp Bauknecht in our lab, in a collaboration with Evelyn Houliston.

  16. In our new preprint we characterise neuropeptide signalling in the cnidarian #Nematostella.
    biorxiv.org/content/10.1101/20
    Daniel Thiel and Luis Yanez-Guerra screened 64 neuropeptides against 161 G-protein coupled receptors (#GPCR) and found activating peptide ligands for 31 receptors.

  18. In dieser Fallserie zur Behandlung von #LongCovid durch #Immunadsorption konnte leider keine Wirksamkeit festgestellt werden.

    Mögliche Ursachen sind
    - Membrangebundene #Autoantikörper konnten nicht entfernt werden.
    - Die Krankheit war bereits chronifiziert.
    - Autoantikörper sind nur ein Epiphänomen.
    - Autoantikörper werden zu schnell nachgebildet.

  20. Once in a while, I still wonder how a #GPCR with a fluorescent protein inserted in ICL3 can do any signaling.

  21. Made our own #GPCR #gingerbread cookies. Few with some serious mutations 😂. h/t @cllantz for the fun cookie cutters

  23. New #preprint about PENSA, our flexible #OpenSource software package for comprehensive and thorough investigation of biomolecular conformational ensembles:

    arxiv.org/abs/2212.02714

    In three real-world examples, we show how it can be used to understand an #enzyme mechanism, #DNA #forcefield parameters, and #signaling in an #opioid #receptor.
