5-Hydroxytryptamine receptor 4 is a protein that in humans is encoded by the HTR4 gene. ^{[5] [6]}

Function

This gene is a member of the family of human serotonin receptors, which are G protein-coupled receptors that stimulate cAMP production in response to serotonin (5-hydroxytryptamine). The gene product is a glycosylated transmembrane protein that functions in both the peripheral and central nervous system to modulate the release of various neurotransmitters. Multiple transcript variants encoding proteins with distinct C-terminal sequences have been described, but the full-length nature of some transcript variants has not been determined. ^[7]

Location

The receptor is located in the alimentary tract, urinary bladder, heart and adrenal gland as well as the central nervous system (CNS). ^[8] In the CNS the receptor appears in the putamen, caudate nucleus, nucleus accumbens, globus pallidus, and substantia nigra, and to a lesser extent in the neocortex, raphe, pontine nuclei, and some areas of the thalamus. It has not been found in the cerebellum. ^[9]

Isoforms

Internalization is isoform-specific. ^[10]

Ligands

Several drugs that act as 5-HT₄ selective agonists have recently been introduced into use in both scientific research and clinical medicine. Some drugs that act as 5-HT₄ agonists are also active as 5-HT₃ antagonists, such as mosapride, metoclopramide, renzapride, and zacopride, and so these compounds cannot be considered highly selective. Research in this area is ongoing. ^[11] Amongst these agonists prucalopride has >150-fold higher affinity for 5-HT4 receptors than for other receptors.

SB-207,145 radiolabeled with carbon-11 is used as a radioligand for 5-HT₄ in positron emission tomography pig ^[12] and human ^[13] studies.
