Previous GeneCards Identifiers for GABRA1 Gene
This gene encodes a gamma-aminobutyric acid (GABA) receptor. 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. GABA-A receptors are pentameric, consisting of proteins from several subunit classes: alpha, beta, gamma, delta and rho. Mutations in this gene cause juvenile myoclonic epilepsy and childhood absence epilepsy type 4. Multiple transcript variants encoding the same protein have been identified for this gene.

GeneCards Summary for GABRA1 Gene
GABRA1 (Gamma-Aminobutyric Acid Type A Receptor Alpha1 Subunit) is a Protein Coding gene. Diseases associated with GABRA1 include Epileptic Encephalopathy, Early Infantile, 19 and Epilepsy, Juvenile Myoclonic 5. Among its related pathways are Apoptosis Pathway and Transmission across Chemical Synapses. GO annotations related to this gene include drug binding and extracellular ligand-gated ion channel activity. An important paralog of this gene is GABRA4.
UniProtKB/Swiss-Prot for GABRA1 Gene
Component of the heteropentameric receptor for GABA, the major inhibitory neurotransmitter in the vertebrate brain. Functions also as histamine receptor and mediates cellular responses to histamine. Functions as receptor for diazepines and various anesthetics, such as pentobarbital; these are bound at a separate allosteric effector binding site. Functions as ligand-gated chloride channel (By similarity).
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.
