G protein-coupled receptor (GPCR) heteromerization is rapidly evolving field. Traditionally, GPCRs were thought to behave has independent entities or protomers. However, that line of reasoning has since been brought into question. Currently, it appears that many, if not all, GPCRs signal and function as heteromeric receptor complexes. The roles of GPCR heteromerization are vast and can include: maturation and trafficking; dynamic regulation; allostery and cooperativity; signal transduction; and receptor internalization.
The majority of studies identifying and characterizing GPCR heteromers were performed using recombinant receptors. Only four receptor pairs have been identified and validated in native tissues. The overall objective of …
