Specificity This antibody recognizes the GABABR1 subunit. The GABAB receptor is the first discovered G-protein-coupled receptor whose function requires two subunits, R1 and R2, to form a functional receptor. The R1 subunit extracellular domain binds GABA, and the R2 subunit functions in G-protein activation.

Target Name γ-aminobutyric acid type B receptor subunit 1

Target ID GABABR1

Uniprot ID Q9UBS5

Alternative Names GABA-B receptor 1, GABA-B-R1, GABA-BR1, GABABR1, Gb1

Gene Name GABBR1

Sequence Location Cell membrane, Cell junction, synapse, postsynaptic cell membrane, Cell projection, dendrite

Biological Function Component of a heterodimeric G-protein coupled receptor for GABA, formed by GABBR1 and GABBR2 (PubMed:9872316, PubMed:9872744, PubMed:15617512, PubMed:18165688, PubMed:22660477, PubMed:24305054). Within the heterodimeric GABA receptor, only GABBR1 seems to bind agonists, while GABBR2 mediates coupling to G proteins (PubMed:18165688). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase (PubMed:10906333, PubMed:10773016, PubMed:10075644, PubMed:9872744, PubMed:24305054). Signaling inhibits adenylate cyclase, stimulates phospholipase A2, activates potassium channels, inactivates voltage-dependent calcium-channels and modulates inositol phospholipid hydrolysis (PubMed:10075644). Calcium is required for high affinity binding to GABA (By similarity). Plays a critical role in the fine-tuning of inhibitory synaptic transmission (PubMed:9844003). Pre-synaptic GABA receptor inhibits neurotransmitter release by down-regulating high-voltage activated calcium channels, whereas postsynaptic GABA receptor decreases neuronal excitability by activating a prominent inwardly rectifying potassium (Kir) conductance that underlies the late inhibitory postsynaptic potentials (PubMed:9844003, PubMed:9872316, PubMed:10075644, PubMed:9872744, PubMed:22660477). Not only implicated in synaptic inhibition but also in hippocampal long-term potentiation, slow wave sleep, muscle relaxation and antinociception (Probable). Activated by (-)-baclofen, cgp27492 and blocked by phaclofen (PubMed:9844003, PubMed:9872316, PubMed:24305054). {UniProtKB:Q9Z0U4, PubMed:10075644, PubMed:10773016, PubMed:10906333, PubMed:15617512, PubMed:18165688, PubMed:22660477, PubMed:24305054, PubMed:9844003, PubMed:9872316, PubMed:9872744, ECO:0000305}.; Isoform 1E may regulate the formation of functional GABBR1/GABBR2 heterodimers by competing for GABBR2 binding. This could explain the observation that certain small molecule ligands exhibit differential affinity for central versus peripheral sites.
