Previous GeneCards Identifiers for GABRR2 Gene
Gamma-aminobutyric acid (GABA) is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA receptors, which are ligand-gated chloride channels. The protein encoded by this gene is a member of the rho subunit family and is a component of the GABA type A receptor complex. This gene exists on chromosome 6q next to the gene encoding the rho 1 subunit of the GABA type A receptor, in a region thought to be associated with susceptibility for psychiatric disorders and epilepsy. Polymorphisms in this gene may also be associated with alcohol dependence, and general cognitive ability. [provided by RefSeq, Apr 2016]
GeneCards Summary for GABRR2 Gene
GABRR2 (Gamma-Aminobutyric Acid Type A Receptor Rho2 Subunit) is a Protein Coding gene. Diseases associated with GABRR2 include alcohol dependence and essential tremor. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and Circadian entrainment. GO annotations related to this gene include protein domain specific binding and extracellular ligand-gated ion channel activity. An important paralog of this gene is GABRR1.
UniProtKB/Swiss-Prot for GABRR2 Gene
GABA, the major inhibitory neurotransmitter in the vertebrate brain, mediates neuronal inhibition by binding to the GABA/benzodiazepine receptor and opening an integral chloride channel. Rho-2 GABA receptor could play a role in retinal neurotransmission.
GABAA-rho receptors, previously known as GABAC receptors, are Cys-loop ionotropic ligand-gated ion channels mediating the fast synaptic inhibitory effects of GABA. Despite differing in pharmacology, physiology and biochemistry, they are viewed as a subclass of GABAA receptors.
