β subunits of GABA A receptors form proton-gated ... To assess ethanol effects on GIRKs coupled to different G-protein-coupled receptors, the GIRK 1 and 4 cRNAs were co-expressed with μ opioid ...

G beta-gamma (purple circles), and a G-protein-coupled receptor (GPCR; light green loops). Upon receptor stimulation by a ligand called an agonist, the state of the receptor changes. G alpha ...

These molecules are key players in health and disease. One such molecular switch is G protein-coupled receptor kinases, or GRKs for short. Their involvement in a broad range of diseases makes GRKs ...

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...
