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

Using purified Fzd proteins reconstituted in lipid nanodiscs, we investigated the factors that promote We found that the affinity of Fzd for Dvl was not affected by Wnt ligands, in contrast to other members of the GPCR superfamily for which the binding of extracellular ligands affects the affinity for downstream Instead, Fzd-Dvl binding was enhanced by increased concentration of the lipid PI(4,5)P2, which is generated by Dvl-associated lipid kinases in response to Wnt and which is required for LRP5/6 phosphorylation.

KISS1R signalling and physiological output in the hormone receptor-negative MDA-MB-231 and BT-20 cell lines MDA-MB-231 cells are metastatic when implanted in mice while BT-20 are not and remain epithelial-like We show that both cell lines express KISS1R mRNA and respond to KP-10 by elevating calcium mobilisation Interestingly, both cell lines displayed different complements of β-arrestin 1 and 2 expression. stimulate migration or pro-metastatic behaviour, as divergent responses were observed in the two TNBC lines

We identified a novel GRK3 inhibitor, LD2, through a chemical-library screen.
