Summaries for HTR3B Gene

Entrez Gene Summary for HTR3B Gene

  • The product of this gene belongs to the ligand-gated ion channel receptor superfamily. This gene encodes subunit B 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 is not functional as a homomeric complex, but a pentaheteromeric complex with subunit A (HTR3A) displays the full functional features of this receptor. [provided by RefSeq, Aug 2011]

GeneCards Summary for HTR3B Gene

HTR3B (5-Hydroxytryptamine Receptor 3B) is a Protein Coding gene. Diseases associated with HTR3B include Gilles De La Tourette Syndrome. Among its related pathways are CREB Pathway and Ligand-gated ion channel transport. GO annotations related to this gene include ion channel activity and G-protein coupled serotonin receptor activity. An important paralog of this gene is HTR3A.

UniProtKB/Swiss-Prot for HTR3B 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. It is a cation-specific, but otherwise relatively nonselective, ion channel.

Tocris Summary for HTR3B 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).
