Previous GeneCards Identifiers for GABRB2 Gene
The gamma-aminobutyric acid (GABA) A receptor is a multisubunit chloride channel that mediates the fastest inhibitory synaptic transmission in the central nervous system. This gene encodes GABA A receptor, beta 2 subunit. It is mapped to chromosome 5q34 in a cluster comprised of genes encoding alpha 1 and gamma 2 subunits of the GABA A receptor. Alternative splicing of this gene generates 2 transcript variants, differing by a 114 bp insertion. [provided by RefSeq, Jul 2008]
GeneCards Summary for GABRB2 Gene
GABRB2 (Gamma-Aminobutyric Acid Type A Receptor Beta2 Subunit) is a Protein Coding gene. Diseases associated with GABRB2 include Heroin Dependence and Lennox-Gastaut Syndrome. Among its related pathways are Ion channel transport and Transmission across Chemical Synapses. GO annotations related to this gene include chloride channel activity and GABA-A receptor activity. An important paralog of this gene is GABRB3.
UniProtKB/Swiss-Prot for GABRB2 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.
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.
