Protein Comments
KCTD proteins act as auxiliary subunits of GABAB receptors that determine the pharmacology and kinetics of the receptor response. GABAB receptors assemble from principle and auxiliary subunits. The principle subunits GABAB1 and GABAB2 form functional heteromeric GABAB(1,2) receptors that associate with homotetramers of auxiliary KCTD8, 12, 12b or 16 (named after their K+ channel tetramerization domain) subunits [1-2].
