Abstract:
Numerous recent studies have suggested that the predicted cytosolic domains of G protein-coupled receptors represent a surface for association with proteins that may serve multiple roles in receptor localization, turnover, and signaling beyond the well-characterized interactions of these receptors with heterotrimeric G proteins. This Chapter describes two in vitro methods for ascertaining interactions between G protein-coupled receptors and various binding partners: gel overlay strategies and GST-fusion protein pull-downs.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
