Abstract
The importance of G protein-coupled receptor (GPCR) receptor–receptor interactions in regulating cell signaling is well documented. However, traditional methods to study these interactions are difficult to multiplex and often require extensive technical expertise and equipment. In this chapter, we will describe the major biochemical and fluorescence microscopy methods to study GPCR–GPCR interactions and introduce an alternative technique that utilizes proximity biotinylation to study these interactions. The goal of this chapter is to provide researchers with a comprehensive protocol to implement this new approach to study GPCR dimerization. Finally, we will compare and contrast the advantages and limitations of the proximity biotinylation assay with established methods to help researchers identify the best approach for their research application.
