Summary: Enables G protein-coupled serotonin receptor activity and serotonin binding activity. Involved in negative regulation of serotonin secretion and phospholipase C-activating serotonin receptor signaling pathway. Acts upstream of or within adenylate cyclase-inhibiting G protein-coupled receptor signaling pathway; bone remodeling; and response to toxic substance. Located in cytoplasm and plasma membrane. Part of G protein-coupled serotonin receptor complex. Is active in presynaptic membrane and serotonergic synapse. Is expressed in several structures, including alimentary system; central nervous system; eye; gonad; and immune system. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; antisocial personality disorder; attention deficit hyperactivity disorder; conduct disorder; and substance abuse (multiple). Orthologous to human HTR1B (5-hydroxytryptamine receptor 1B). [provided by Alliance of Genome Resources, Dec 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.
