Previous GeneCards Identifiers for GABRA2 Gene
GABA is the major inhibitory neurotransmitter in the mammalian brain where it acts at GABA-A receptors, which are ligand-gated chloride channels. Chloride conductance of these channels can be modulated by agents such as benzodiazepines that bind to the GABA-A receptor. At least 16 distinct subunits of GABA-A receptors have been identified. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2013]
GeneCards Summary for GABRA2 Gene
GABRA2 (Gamma-Aminobutyric Acid Type A Receptor Alpha2 Subunit) is a Protein Coding gene. Diseases associated with GABRA2 include alcohol dependence and spinocerebellar ataxia 40. 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 chloride channel activity and GABA-A receptor activity. An important paralog of this gene is GABRA4.
UniProtKB/Swiss-Prot for GABRA2 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.
GABAA receptors are members of the Cys-loop family of ligand-gated ion channels and, along with GABAB receptors, are responsible for mediating the inhibitory effects of GABA. They are pentameric proteins, consisting of five subunits belonging to different families.
