Summary: Enables transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Predicted to be involved in several processes, including GABAergic synaptic transmission; chloride transmembrane transport; and inhibitory synapse assembly. Is active in GABA-ergic synapse and postsynaptic specialization membrane. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and immune system. Human ortholog(s) of this gene implicated in bipolar disorder and multiple sclerosis. Orthologous to human GABRA3 (gamma-aminobutyric acid type A receptor subunit alpha3).

The alpha3 subunit expression in late adulthood (18months old) is accompanied by an increase in the expression of inflammatory markers within the mouse colon. Knockout mouse studies show that the GABAAR alpha3 subunit plays a role in mediating the colonic inflammation associated with the process of ageing.

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.
