Figure 5. GIRK1–GIRK2 chimeras confirm the role of G1-dCT in Gβγ recruitment and high Ibasal.
A, cartoon presentation of the two chimeric channels used. The GIRK1*–dCTG2 chimera shows small basal currents (B) and is unable to recruit Gβγ to the PM (C), while GIRK2–dCTG1 shows large basal currents and recruits Gβγ. *P < 0.05, ***P < 0.001.
