Figure 5. BRET between Gαi1-RLuc donors and tetracysteine-tagged D4DR.
HEK 293 cells co-expressing β2AR, Gαs, Gβ1, Gγ2, AC and the indicated combination of tetracystein-tagged D4DR and Gαi1-RLuc were treated as described in Fig. 3. The BRET background was determined in cells co-expressing D4DR that lacked a tetracysteine tag. The data is representative of five independent experiments.
