5-Hydroxytryptamine receptor 4 is a protein that in humans is encoded by the HTR4 gene.[1][2]

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.[3]

Location

The receptor is located in the alimentary tract, urinary bladder, heart and adrenal gland as well as the central nervous system (CNS).[4] 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.[5]

Isoforms

Internalization is isoform-specific.[6]

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.[7]

SB-207,145 radiolabeled with carbon-11 is used as a radioligand for 5-HT4 in positron emission tomography pig[8] and human[9] studies.
