5-HT6 receptor - Wikipedia
The 5HT 6 receptor is a subtype of 5HT receptor that binds the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5HT). [5] It is a G protein-coupled receptor (GPCR) that is coupled to G s and mediates excitatory neurotransmission. [5] HTR6 denotes the human gene encoding for the receptor. [6]
5-HT6 Receptor - an overview | ScienceDirect Topics
The 5-HT6 receptor is a type of serotonin receptor that belongs to the G-protein-coupled receptor family, stimulating adenylate cyclase and increasing cAMP signaling cascades in the brain. It plays a modulatory role in neurotransmitter systems and shows potential as a therapeutic target for various central nervous system disorders.
