The 5-HT 1B receptor as an example of a metabotropic serotonin receptor. Its crystallographic structure in ribbon representation. 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems.
The 5-HT 3 receptor belongs to the Cys-loop superfamily of ligand ... The 5-HT 3 receptor differs markedly in structure and mechanism from the other 5-HT ...
Except for the serotonin 5-HT 3 receptor, a ligand-gated ion channel, all other 5-HT receptors are G-protein-coupled receptors (also called seven-transmembrane, or heptahelical receptors) that activate an intracellular second messenger cascade. [42] The 5-HT 5B receptor is present in rodents but not in humans.
The 5-HT 2A receptor is a subtype of the 5-HT 2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR). [4] The 5-HT 2A receptor is a cell surface receptor, [5] but has several intracellular locations. [6] Like all 5-HT 2 receptors, the 5-HT 2A receptor is G q /G 11-protein coupled.
The 5-HT 1 receptors are a subfamily of the 5-HT serotonin receptors that bind to the endogenous neurotransmitter serotonin (also known as 5-hydroxytryptamine, or 5-HT). [1] The 5-HT 1 subfamily consists of five G protein-coupled receptors (GPCRs) that share 40% to 63% overall sequence homology, including 5-HT 1A, 5-HT 1B, 5-HT 1D, 5-HT 1E, and 5-HT 1F. [2]

The structure of the 5-HT 2B receptor was resolved in a complex with the valvulopathogenic drug ergotamine. [26] As of 2009, few highly selective 5-HT 2B receptor ligands have been discovered, although numerous potent non-selective compounds are known, particularly agents with concomitant 5-HT 2C binding.
