The signals of cells and their environments often involve molecules or ligands that bind to a receptor, which can trigger a biochemical process in a cell. G protein-coupled receptors (GPCRs) sit in ...

Structural findings reveal how distinct GPCR ligands create different levels of activation
G-protein coupled receptors (GPCRs) are proteins triggered by ligands (protein-binding chemicals) from outside cells to transmit signals inside the cell. These signals are transmitted primarily ...
BACKGROUND: Despite antiplatelet therapy, some patients remain at high ischemic risk because of drug nonresponsiveness or high residual platelet reactivity). We aimed to target an orphan platelet GPCR ...
The study also clarifies the functional role of the receptor's conserved sodium-binding pocket, showing that sodium egress strongly promotes activation-related conformational states, including a ...
A multinational research team led by researchers at Institute of Science Tokyo, RIKEN, and the University of Toronto has revealed how a tryptophan-rich allosteric communication network regulates ...
