Summary: Enables transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Contributes to GABA-gated chloride ion channel activity. Involved in inhibitory synapse assembly. Located in plasma membrane. Is active in GABA-ergic synapse. Is expressed in central nervous system; eye; palatal shelf; and submandibular gland primordium. Used to study idiopathic generalized epilepsy. Human ortholog(s) of this gene implicated in developmental and epileptic encephalopathy 19 and idiopathic generalized epilepsy 13. Orthologous to human GABRA1 (gamma-aminobutyric acid type A receptor subunit alpha1). [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.
