Summary: Predicted to enable GABA-gated chloride ion channel activity and transmitter-gated monoatomic ion channel activity involved in regulation of postsynaptic membrane potential. Predicted to contribute to GABA-A receptor activity; benzodiazepine receptor activity; and chloride channel activity. Acts upstream of or within central nervous system development. Predicted to be located in postsynaptic membrane. Predicted to be part of GABA-A receptor complex. Predicted to be active in GABA-ergic synapse; dendrite membrane; and postsynaptic specialization membrane. Is expressed in several structures, including alimentary system; brain; eye; genitourinary system; and spinal cord. Human ortholog(s) of this gene implicated in autistic disorder. Orthologous to human GABRA4 (gamma-aminobutyric acid type A receptor subunit alpha4). [provided by Alliance of Genome Resources, Dec 2024]

These data suggest that pubertal synaptic pruning requires alpha4betadelta GABA-A receptors.

Title: GABA(A) receptor α(4)-subunit knockout enhances lung inflammation and airway reactivity in a murine asthma model.
Rindings suggest that knock-out of the GABAR alpha4 subunit restores synaptic plasticity and spatial learning at puberty and is consistent with the concept that the dendritic alpha4betadelta GABARs which emerge at puberty selectively impair central nervous system plasticity.

alpha4 subunit expression strongly influences the pubertal increase of delta subunits at the plasma membrane, and that genetic deletion of alpha4 serves as a functional knock-down of delta-containing GABARs.

Data suggest that the availability of distinct GABA(A) R subtypes (Gabra2, -4, and Gabrd) provides a molecular mechanism endowing spatiotemporal specificity to GABAergic control of neuronal maturation in adult brain.

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.
