  • FunctionThis 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.
  • Tissue specificityExpressed in the brain cortex, in the caudate nucleus, the hyppocampus, the thalamus and the amygdala. Detected in the kidney and testis as well as in monocytes of the spleen, small and large intestine, uterus, prostate, ovary and placenta.
  • Sequence similaritiesBelongs to the ligand-gated ion channel (TC 1.A.9) family. 5-hydroxytryptamine receptor (TC 1.A.9.2) subfamily. HTR3B sub-subfamily.
  • Post-translational
    N-glycosylation required for membrane localization.
  • Cellular localizationCell membrane. Presumably retained within the endoplasmic reticulum unless complexed with HTR3A.
