  • Title: Bimolecular fluorescence complementation analysis of G protein-coupled receptor dimerization in living cells.
    Author: Ejendal KF, Conley JM, Hu CD, Watts VJ.
    Journal: Methods Enzymol; 2013; 521():259-79. PubMed ID: 23351744.
    Abstract:
    Emerging evidence indicates that G protein-coupled receptor (GPCR) signaling is mediated by receptor-receptor interactions at multiple levels. Thus, understanding the biochemistry and pharmacology of those receptor complexes is an important part of delineating the fundamental processes associated with GPCR-mediated signaling in human disease. A variety of experimental approaches have been used to explore these complexes, including bimolecular fluorescence complementation (BiFC) and multicolor BiFC (mBiFC). BiFC approaches have recently been used to explore the composition, cellular localization, and drug modulation of GPCR complexes. The basic methods for applying BiFC and mBiFC to study GPCRs in living cells are the subject of the present chapter.
