Summaries for HTR3A Gene

Entrez Gene Summary for HTR3A Gene

  • 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]

GeneCards Summary for HTR3A Gene

HTR3A (5-Hydroxytryptamine Receptor 3A) is a Protein Coding gene. Diseases associated with HTR3A include motion sickness and serotonin syndrome. Among its related pathways are Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds and SIDS Susceptibility Pathways. GO annotations related to this gene include receptor activity and extracellular ligand-gated ion channel activity. An important paralog of this gene is HTR3D.

UniProtKB/Swiss-Prot for HTR3A Gene

  • 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.

Tocris Summary for HTR3A Gene

  • Serotonin 5-HT3 receptors, are ligand-gated ion channels of the Cys-loop family. The receptor consists of four transmembrane domains that form an intrinsic cation-selective channel. So far five human 5-HT3 receptor subtypes have been identified (5-HT3A-E).

    Quaternary structure:
    • Forms pentahomomeric complex as well as pentaheteromeric complex with HTR3B or HTR3C or HTR3D or HTR3E; homomeric complex is functional but exhibits low conductance with modified voltage dependence, and decreased agonist and antagonist affinity. Interacts with RIC3.
    Miscellaneous:
    • The HA-stretch region of HTR3A seems to be responsible for the low conductance of HTR3A homomers compared to that of HTR3A/HTR3B heteromers.
