Gabra3 - gamma-aminobutyric acid (GABA) A receptor, subunit alpha 3

Enables transmitter-gated 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 gamma-aminobutyric acid signaling pathway. Predicted to act upstream of or within ion transport. Located in GABA-ergic synapse. Is integral component of 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).
