Summary: Enables GABA-A receptor activity and chloride channel activity. Contributes to GABA receptor activity. Involved in several processes, including GABAergic synaptic transmission; cellular response to zinc ion; and response to anesthetic. Located in cell surface; dendrite membrane; and inhibitory synapse. Part of GABA receptor complex. Is active in GABA-ergic synapse; glutamatergic synapse; and postsynaptic specialization membrane. Biomarker of fetal alcohol spectrum disorder and hepatic encephalopathy. Human ortholog(s) of this gene implicated in alcohol dependence; alcoholic liver cirrhosis; amphetamine abuse; brain disease (multiple); and heroin dependence. Orthologous to human GABRG2 (gamma-aminobutyric acid type A receptor subunit gamma2). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
