Summary: Enables G protein-coupled GABA receptor activity; extracellular matrix protein binding activity; and protein heterodimerization activity. Involved in several processes, including negative regulation of adenylate cyclase activity; neuron-glial cell signaling; and regulation of secretion. Acts upstream of or within adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway. Located in several cellular components, including axolemma; dendrite; and synaptic vesicle. Is integral component of plasma membrane. Part of GABA receptor complex. Is active in GABA-ergic synapse and glutamatergic synapse. Is integral component of postsynaptic membrane and integral component of presynaptic membrane. Used to study visual epilepsy. Biomarker of hypertension and visual epilepsy. Orthologous to human GABBR1 (gamma-aminobutyric acid type B receptor subunit 1). [provided by Alliance of Genome Resources, Apr 2022]

We demonstrate that GABABR activation can regulate KCC2 at the cell surface in a manner that alters intracellular chloride and the reversal potential for the GABAAR. Our data therefore support an additional mechanism by which GABABRs are able to modulate fast synaptic inhibition.
Title: Neuronal Chloride Regulation via KCC2 Is Modulated through a GABA(B) Receptor Protein Complex.
sustained activation of glutamate receptors, a condition occurring in brain ischemia that down-regulates GABAB receptors, considerably increased the expression of MIB2 and Lys-63-linked ubiquitination of GABAB receptors. Interfering with Lys-63-linked ubiquitination by overexpressing ubiquitin mutants or GABAB1 mutants deficient in Lys-63-linked ubiquitination prevented glutamate-induced down-regulation of the receptors.

Both synaptic processes were critically dependent on activation of GABAB receptors and, together, appeared to temporally segregate the cortical representation. These data suggest that adaptation to repetitive sensory input dramatically alters the spatiotemporal properties of the neocortical response in a manner that may both refine and minimize cortical output simultaneously.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
