Native expression of RGS6, Gβ5, GABABR2, GIRK1, and GIRK2 in isolated CGNs.
A, RGS6 immunostaining is localized to the soma and neurites of CGNs from WT mice and absent in RGS6−/− mice. B, co-immunostaining of RGS6 with Gβ5, GABABR2, GIRK1, and GIRK2 in CGNs from WT mice (scale bar = 100 μm; white arrows, regions of overlapping expression of RGS6 with indicated protein).
