KCTD8, KCTD12, and KCTD16 proteins bind to G protein 尾纬 subunits
KCTD12 uncouples 尾纬 subunits from K+ channels to desensitize the current response
KCTD12 protein in the brain is exclusively associated with GABAB receptors
GABAB receptors produce receptor-specific desensitization by harnessing KCTD12
