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 (GABA) A Receptor, Alpha 1) 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 Akt Signaling and Apoptosis Pathway. 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, responsible for mediating the inhibitory effects of GABA alongside GABAB and GABAC receptors. They are pentameric proteins, consisting of 5 subunits belonging to different families (alpha1-6, beta1-3, gamma1-3, delta, pi, epsilon, rho, theta). The most abundant GABAA receptor in the mammalian brain consist of two copies each of alpha1 and beta2 with a single gamma2 subunits. GABAA receptors contain an integral chloride channel, and have modulatory sites for benzodiazepines, barbiturates, neurosteroids and ethanol.
