Summaries for GABRB1 Gene

Entrez Gene Summary for GABRB1 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 1 subunit. It is mapped to chromosome 4p12 in a cluster comprised of genes encoding alpha 4, alpha 2 and gamma 1 subunits of the GABA A receptor. Alteration of this gene is implicated in the pathogenetics of schizophrenia. [provided by RefSeq, Jul 2008]

GeneCards Summary for GABRB1 Gene

GABRB1 (Gamma-Aminobutyric Acid (GABA) A Receptor, Beta 1) is a Protein Coding gene. Diseases associated with GABRB1 include schizophrenia. 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 GABRB1 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).

Tocris Summary for GABRB1 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.
