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. Predicted to act upstream of or within central nervous system development. Is active in GABA-ergic synapse and postsynaptic specialization membrane. Human ortholog(s) of this gene implicated in autistic disorder. Orthologous to human GABRA4 (gamma-aminobutyric acid type A receptor subunit alpha4).

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.
