Our data revealed the following new information on the G-protein coupling of the heteromeric GABAB receptor: 1) the i2 loop of GB2 within the GB2 HD is required for the heteromeric GABAB receptor to couple to G-proteins, whereas the i2 loop of GB1 is not; 2) the presence of the i2 loop of GB2 within the GB1 HD is not sufficient to allow coupling of GB1; 3) the GB2 HD activates the Gqi9 protein whether it is associated with the GB2 or GB1 ECD; 4) in the combination with two GB2 HDs, each is able to couple to G-proteins.
