Summaries for GABRB3 Gene

Entrez Gene Summary for GABRB3 Gene

  • This gene encodes a member of the ligand-gated ionic channel family. The encoded protein is one the subunits of a multi-subunit chloride channel that serves as the receptor for gamma-aminobutyric acid, a major inhibitory neurotransmitter of the mammalian nervous system. This gene is located on the long arm of chromosome 15 in a cluster with two other genes encoding related subunits of the family. This gene may be associated with the pathogenesis of several disorders including Angelman syndrome, Prader-Willi syndrome, nonsyndromic orofacial clefts, epilepsy and autism. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Jul 2013]

GeneCards Summary for GABRB3 Gene

GABRB3 (Gamma-Aminobutyric Acid (GABA) A Receptor, Beta 3) is a Protein Coding gene. Diseases associated with GABRB3 include epilepsy, childhood absence 5 and childhood disintegrative disease. Among its related pathways are Akt Signaling and Apoptosis Pathway. GO annotations related to this gene include chloride channel activity and GABA-A receptor activity. An important paralog of this gene is GABRR1.

UniProtKB/Swiss-Prot for GABRB3 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.

Tocris Summary for GABRB3 Gene

  • 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.
