Previous GeneCards Identifiers for HTR3D Gene
The protein encoded this gene belongs to the ligand-gated ion channel receptor superfamily. This gene encodes subunit D of the type 3 receptor for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a mitogen and a hormone. This hormone has been linked to neuropsychiatric disorders, including anxiety, depression, and migraine. Serotonin receptors causes fast and depolarizing responses in neurons following activation. The genes encoding subunits C, D and E of this type 3 receptor form a cluster on chromosome 3. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

GeneCards Summary for HTR3D Gene
HTR3D (5-Hydroxytryptamine (Serotonin) Receptor 3D, Ionotropic) is a Protein Coding gene. Among its related pathways are CREB Pathway and Transport of glucose and other sugars, bile salts and organic acids, metal ions and amine compounds. GO annotations related to this gene include extracellular ligand-gated ion channel activity and serotonin receptor activity. An important paralog of this gene is HTR3A.
UniProtKB/Swiss-Prot for HTR3D 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
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).
