Protein name:
Gamma-aminobutyric acid type B receptor subunit 1 (GABA-B receptor 1;GABA-B-R1;GABA-BR1;GABABR1;Gb1) ;
Alternative:
Organism:
Rat (Rattus norvegicus).
General Annotation
Sub Unit:
Heterodimer of GABA-B-R1 and GABA-B-R2. Neither of which is effective on its own and homodimeric assembly does not seem to happen. Interacts with the leucine zipper of the C-terminal bZIP domain of ATF4 via its C-terminal region. Interacts with JAKMIP1.
Function:
Receptor for GABA. The activity of this receptor is mediated by G-proteins that inhibit adenylyl cyclase activity, stimulates phospholipase A2, activates potassium channels, inactivates voltage-dependent calcium-channels and modulates inositol phospholipids hydrolysis. Plays a critical role in the fine-tuning of inhibitory synaptic transmission. Pre-synaptic GABA-B-R inhibit neurotransmitter release by down-regulating high-voltage activated calcium channels, whereas postsynaptic GABA-B-R decrease neuronal excitability by activating a prominent inwardly rectifying potassium (Kir) conductance that underlies the late inhibitory postsynaptic potentials. Not only implicated in synaptic inhibition but also in hippocampal long-term potentiation, slow wave sleep, muscle relaxation and antinociception.
Subcellular Location:
Cell membrane
Multi-pass membrane protein
Cell junction
synapse
postsynaptic cell membrane
Multi-pass membrane protein
Moreover coexpression of GABA-B-R1 and GABA-B-R2 appears to be a prerequisite for maturation and transport of GABA-B-R1 to the plasma membrane. Colocalizes with ATF4 in hippocampal neuron dendritic membranes.
