Figure 3

Concentration-response curve of WIN55,212-2 for CB-GIRK1/2-RGS4 coupling and GIRK1/2. Oocytes were co-injected with CB, GIRK1/2, and RGS4, or GIRK1/2 cRNAs. Inward K+ current enhancement and reduction were produced on the application of a range of different concentrations of WIN55,212-2 in the presence of HK. The positive percentage represents enhancement and the negative percentage represents reduction. Each data point is the mean ± standard deviation (SD) of three determinations from two or three batches of oocytes.
