Serotonin Receptor 5-HT6 (5-HT6R)

Target
5-HT6R
Molecular classification
G protein-coupled receptor, Receptor
01

Overview

The serotonin receptor 5-HT6 (5-HT6R) is a G protein-coupled receptor primarily expressed in the brain. It binds serotonin and modulates the activity of other neurotransmitter systems, including glutamate, acetylcholine, dopamine, norepinephrine, and GABA. It is implicated in cognitive and psychiatric disorders and is a target for drug development for Alzheimer's disease, schizophrenia, depression, anxiety, OCD, and obesity.

Other names
5-hydroxytryptamine receptor 65HT6 receptor
