Serotonylation is a receptor independent signaling mechanism by which serotonin activates intracellular processes by creating long lasting covalent bonds upon proteins. [1] It occurs through the modification of proteins by the attachment of serotonin on their glutamine residues.

Serotonin pathways are thought to modulate eating, both the amount as well as the motor processes associated with eating. The serotonergic projections into the hypothalamus are thought to be particularly relevant, and an increase in serotonergic signaling is thought to generally decrease food consumption (evidenced by fenfluramine , however ...
The serotonin created by the brain comprises around 10% of total body serotonin. The majority (80-90%) is found in the gastrointestinal (GI) tract. [15] [16] It travels around the brain along the medial forebrain bundle and acts on serotonin receptors. In the peripheral nervous system (such as in the gut wall) serotonin regulates vascular tone.
The 7 general serotonin receptor classes include a total of 14 known serotonin receptors. [9] The 15th receptor 5-HT 1P has been distinguished on the basis of functional and radioligand binding studies, its existence has never been definitely affirmed or refuted. [10] [11] The specific types have been characterized as follows: [12] [13] [14]
The 5-HT 2 receptors are a subfamily of 5-HT receptors that bind the endogenous neurotransmitter serotonin (5-hydroxytryptamine, 5-HT). [1] The 5-HT 2 subfamily consists of three G protein-coupled receptors (GPCRs) which are coupled to G q /G 11 and mediate excitatory neurotransmission, [2] including 5-HT 2A, 5-HT 2B, and 5-HT 2C.
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.
