GABRB1

Gamma-aminobutyric acid receptor subunit beta-1 is a is_associated_with::protein that in humans is encoded by the GABRB1 is_associated_with::gene.

Function
The gamma-aminobutyric acid A receptor (GABAA 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 GABAA receptor. Alteration of this gene is implicated in the pathogenetics of schizophrenia.

Clinical significance
Mice bearing mutant copies of this gene have been shown to be vulnerable to is_associated_with::binge drinking of alcohol.
