Gabrb3 - gamma-aminobutyric acid (GABA) A receptor, subunit beta 3

Enables GABA-A receptor activity and transmitter-gated ion channel activity involved in regulation of postsynaptic membrane potential. Contributes to GABA-gated chloride ion channel activity. Involved in several processes, including chloride transmembrane transport; inner ear development; and nervous system development. Acts upstream of or within several processes, including cellular response to zinc ion; circadian sleep/wake cycle, REM sleep; and learning or memory. Located in GABA-ergic synapse and plasma membrane. Part of GABA-A receptor complex. Is active in cell surface. Is expressed in several structures, including central nervous system; eye; jaw; and olfactory epithelium. Used to study autism spectrum disorder. Human ortholog(s) of this gene implicated in childhood absence epilepsy and developmental and epileptic encephalopathy 43. Orthologous to human GABRB3 (gamma-aminobutyric acid type A receptor subunit beta3). [provided by Alliance of Genome Resources, Apr 2022]
