14966130 Association of the GABA(B)R1 with the GABA(A) receptor gamma2S subunit robustly promotes cell surface expression of GABA(B)R1 in the absence of GABA(B)R2, that is usually required for efficient trafficking of GABA(B)R1 to the cell surface.
14961561 GABA(B) receptor subunit GABA(B)R2 is found on the same neurons and follows the same distribution patterns in the basal ganglia as the GABABR1 receptor subunit.
