Summary: Enables several functions, including G protein-coupled serotonin receptor activity; G-protein alpha-subunit binding activity; and serotonin binding activity. Involved in several processes, including NMDA glutamate receptor clustering; adenylate cyclase-inhibiting serotonin receptor signaling pathway; and behavioral response to nicotine. Located in axon hillock. Is active in GABA-ergic synapse and presynaptic membrane. Used to study Parkinson's disease; alcohol use disorder; and panic disorder. Biomarker of anxiety disorder; cocaine abuse; nicotine dependence; and subacute delirium. Human ortholog(s) of this gene implicated in alcohol dependence; anxiety disorder (multiple); depressive disorder; substance abuse; and withdrawal disorder. Orthologous to human HTR1A (5-hydroxytryptamine receptor 1A). [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.
