Gamma-aminobutyric acid receptor subunit beta-1 is a protein that in humans is encoded by the GABRB1 gene. ^[5]

Function

The gamma-aminobutyric acid A receptor (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 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. ^[5]

Clinical significance

Mice bearing mutant copies of this gene have been shown to be vulnerable to binge drinking of alcohol. ^[6]
