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 Substance Abuse. Among its related pathways are Peptide ligand-binding receptors 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 GABRA1.
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.
