About This Section

Entrez Gene summary for HTR3A:
The product of this gene belongs to the ligand-gated ion channel receptor superfamily. This gene encodes subunit A of
the type 3 receptor for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a
hormone, and a mitogen. This receptor causes fast, depolarizing responses in neurons after activation. It appears that
the heteromeric combination of A and B subunits is necessary to provide the full functional features of this receptor,
since either subunit alone results in receptors with very low conductance and response amplitude. Alternatively
spliced transcript variants encoding different isoforms have been identified. (provided by RefSeq, Jul 2008)

UniProtKB/Swiss-Prot: 5HT3A_HUMAN, P46098
Function: This is one of the several different receptors for 5-hydroxytryptamine (serotonin), a biogenic hormone that
functions as a neurotransmitter, a hormone, and a mitogen. This receptor is a ligand-gated ion channel, which when
activated causes fast, depolarizing responses in neurons. It is a cation-specific, but otherwise relatively
nonselective, ion channel

summary for HTR3A:
Serotonin 5-HT3 receptors, are ligand-gated ion channels of the Cys-loop family. The receptor consists of
4-transmembrane domains that form an intrinsic cation-selective channel. So far five human 5-HT3 receptor
subtypes have been identified (5-HT3A-E). The 5-HT3B-E subtypes do not form functional homo-oligomeric
complexes like the 5-HT3A subtypes, but co-assemble with 5-HT3A to influence its functional expression.
