    Summary
    Predicted to enable G protein-coupled GABA receptor activity and protein heterodimerization activity. Predicted to be involved in adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway; gamma-aminobutyric acid signaling pathway; and neuron-glial cell signaling. Located in cytoplasm and neuron projection. Is expressed in brain; eye; and liver. Human ortholog(s) of this gene implicated in alcohol use disorder; developmental and epileptic encephalopathy 59; and nicotine dependence. Orthologous to human GABBR2 (gamma-aminobutyric acid type B receptor subunit 2). [provided by Alliance of Genome Resources, Nov 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.
