GPR156

GPR156 (G protein-coupled receptor 156), is a human gene which encodes a G protein-coupled receptor belonging to metabotropic glutamate receptor subfamily. By sequence homology, this gene was proposed as being a possible GABA_B receptor subunit, however when expressed in cells alone or with other GABA_B subunits, no response to GABA_B ligands could be detected. Therefore, the function of this protein remains to be elucidated.
