5-HT, serotonin, receptors are found on the membrane of neurons in the central nervous system and peripheral nervous system. These receptors allow for the body to respond to serotonin and regulate many biological pathways. 5-HT receptors are classified into 7 different subfamilies (5-HT1, 5-HT2, 5-HT3, etc.) by signaling mechanisms and homology of structure. All 5-HT receptors are known to have G-protein linked pathways except for the 5-HT3 receptor which acts as an ion channel. (Wang, et al. 2013). | 5-HT, serotonin, receptors are found on the membrane of neurons in the central nervous system and peripheral nervous system.

5-HT1B: This receptor couples to G-protein alpha subunits Gi and Go. In the central nervous system, this receptor is an inhibitory presynaptic receptor that can alter the release of serotonin, as well as other neurotransmitters, from the presynaptic neuron. The structure of this receptor includes 7 transmembrane alpha-helices in its center. The N-terminal tail of 5-HT1B is close to the ligand binding pocket suggesting some interaction with its ligand. The orthosteric, unmodulated, binding pocket is characterized as a cavity formed from residues of the 3rd, 5th, 6th, and 7th alpha helices and the 2nd extracellular loop.
