Anionic phospholipids determine G protein coupling selectivity at distinct subcellular membrane compartments
E. H. Hernandez, A. Manglik, R. Irannejad
This study shows that anionic phospholipids like PI(4,5)P2 enable promiscuous GPCR coupling to both cognate and non-cognate G proteins at the plasma membrane, while restricting coupling to cognate G proteins in other compartments.
