Summary: Enables ligand-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential. Involved in modulation of chemical synaptic transmission. Located in plasma membrane. Is active in several cellular components, including GABA-ergic synapse; glutamatergic synapse; and presynaptic membrane. Is expressed in brain; cerebral cortex; and retina. Orthologous to human GABRR1 (gamma-aminobutyric acid type A receptor subunit rho1). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

GABRR1 is a rho subunit receptor of GABA, the major inhibitory neurotransmitter in the mammalian brain. The GABA receptor GABRR1 is expressed on and functional in hematopoietic stem cells and megakaryocyte progenitors.

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.
