Summary: Enables G protein-coupled serotonin receptor activity. Involved in several processes, including behavioral fear response; serotonin metabolic process; and serotonin receptor signaling pathway. Acts upstream of or within gamma-aminobutyric acid signaling pathway. Predicted to be located in axon hillock. Predicted to be active in dendrite. Predicted to be integral component of plasma membrane. Is expressed in several structures, including central nervous system; exocrine gland; eye; genitourinary system; and intestine. Used to study anxiety disorder. Human ortholog(s) of this gene implicated in anxiety disorder; mental depression; and panic disorder. Orthologous to human HTR1A (5-hydroxytryptamine receptor 1A).

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.
