Also known as: 5-HT3B
Summary: Enables serotonin-gated cation-selective channel activity. Predicted to be involved in several processes, including chemical synaptic transmission; positive regulation of ion transmembrane transporter activity; and regulation of membrane potential. Predicted to act upstream of or within ion transport. Is integral component of plasma membrane. Is expressed in several structures, including adrenal gland; genitourinary system; gut; lung; and nervous system. Human ortholog(s) of this gene implicated in alcohol use disorder and mental depression. Orthologous to human HTR3B (5-hydroxytryptamine receptor 3B).

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.
