GPR156 Membrane Protein Introduction

Introduction of GPR156

GPR156 is encoded by the GPR156 gene which is located at 3q13.33. The mass of GPR156 is 89,097 Da. It belongs to the G-protein-coupled receptors (GPCRs) which are a large superfamily of cell membrane receptors that are characterized by 7 helical transmembrane domains, together with N-terminal extracellular and C-terminal intracellular domains. The alternative names of GPR156 in the literature are GABABL (GABAB-related G-protein coupled receptor) and PGR28.

Function of GPR156 Membrane Protein

GPR156 belongs to metabotropic glutamate receptor subfamily which are class C G-protein-coupled receptors that respond to the neurotransmitter glutamate. GPR156 functions as a G-protein coupled GABA receptor which means combining with the amino acid gamma-aminobutyric acid (GABA, 4-aminobutyrate) and transmitting the signal across the membrane by activating an associated G-protein, promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. Beyond that, GPR156 has significant homology to the GABAB receptor subunits. GPR156 showed a considerable ubiquitous expression both in the CNS and in peripheral tissues. And the level of GPR156 mRNA observed in fetal brain is about 20-fold higher than that in the adult brain, it reveals a potential role for GPR156 in neural development.
