In the presence of its ligand, we show significant upregulation of H2R nuclear translocation kinetics In this aspect, our present data shed new light on the unexplored H2R signaling mechanisms.

These structures reveal an agonist binding site for the oxysterol and a potential ligand entrance site exposed to the lipid bilayer. Together, these findings provide new insight into how EBI2 is activated by an oxysterol ligand and will facilitate the development of therapeutic approaches that target EBI2-linked diseases."

The fusion strategies explored here are likely applicable to cryo-EM interrogation of other GPCRs and

During Drosophila embryonic salivary gland (SG) invagination, the GPCR ligand Folded gastrulation (Fog Our data support a model wherein Smog regulates distinct myosin pools and actin cytoskeleton in a ligand-dependent

Electroretinography showed restoration of visual function in all three transgenic Gγ1-deficient lines In all dark-adapted transgenic lines, Gαt1 was targeted to the outer segments, reversing its diffuse However, Gαt1 translocation in Gγ11 transgenic mice occurred at significantly dimmer background light retina-specific Gγ isoforms by the ubiquitous Gγ11 affects the ability of rods to adapt to background light

conformational ensemble of CX3C chemokine receptor 1 (CX3CR1) and its interactions with antagonist and agonist ligands receptor 1 (CX3CR1), a member of the class A of G Protein-Coupled Receptors (GPCR) superfamily, and its ligand characterize the conformational ensemble of the receptor in the presence of its antagonist and agonist ligands the receptor conformational changes and described interactions within its key regions and the bounded ligands

dual contrasting functional feature of CBD, that is, displaying antagonistic and (possible) agonistic ligand From microsecond-length unbiased molecular dynamics simulations, we found that the presence of the CBD ligand contrast, when the GPR55 receptor is simulated in complex with the selective agonist ML186, agonist-like These results are in agreement with the proposed modulatory function of each ligand, showing that the The all-atom MD simulations reveal that CBD induces conformational changes linked with agonist-bound

Additionally, we employed optical assays in living cells to thoroughly profile both GPR35 isoforms for constitutive and ligand-induced activation and signaling of 10 different heterotrimeric G proteins, ligand-induced arrestin recruitment, and receptor internalization. Our results reveal that the extended N-terminus of the long isoform limits G protein activation yet elevates and mechanistic insights of our study provide clues for the future design of isoform-specific GPR35 ligands
