Conformational ensemble view of G protein-coupled receptors and the effect of mutations and ligand binding.

Abstract excerpt

G protein-coupled receptors (GPCRs) are integral membrane proteins that can convert an extracellular signal into multiple intracellular signaling processes. This pleiotropy of GPCRs is enabled by their structural flexibility manifested in thermally accessible multiple conformations, each of which may be capable of activating a different signaling cascade inside the cell (Kenakin & Miller, 2010). Different subsets...
