Summaries for GABRA3 Gene

Entrez Gene Summary for GABRA3 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for GABRA3 Gene

GABRA3 (Gamma-Aminobutyric Acid Type A Receptor Alpha3 Subunit) is a Protein Coding gene. Diseases associated with GABRA3 include Thyrotoxic Periodic Paralysis and Rett Syndrome. Among its related pathways are Transmission across Chemical Synapses and GABAergic synapse. Gene Ontology (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 GABRA3 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.

Tocris Summary for GABRA3 Gene

  • 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.
