When inactive, these subunits are found in a trimeric complex...transducer complex consists of a trimer of three subunits: alpha, beta, and gamma (Gα, Gβ, and Gγ), collectively... the GPCR, leading to the activation of the Gα subunit. The activated Gα exchanges bound GDP with GTP,...GTP, resulting in the disassociation of the Gα subunit from the Gβγ dimer, activating downstream signaling.... With binding of the drug, the alpha and beta subunits dissociate resulting in decreased BRET2 signal... are then treated with the luminescent enzyme substrate coelenterazine, followed by the addition of the...
