Predicted to enable GABA receptor binding activity and extracellular ligand-gated ion channel activity. Predicted to contribute to GABA-A receptor activity; benzodiazepine receptor activity; and chloride channel activity. Involved in several processes, including inner ear development; innervation; and sensory perception of sound. Acts upstream of or within associative learning and behavioral fear response. Located in cell body and dendrite. Is expressed in brain. Human ortholog(s) of this gene implicated in bipolar disorder; developmental and epileptic encephalopathy 79; and mental depression. Orthologous to human GABRA5 (gamma-aminobutyric acid type A receptor subunit alpha5). [provided by Alliance of Genome Resources, Apr 2022]
