Serotonin (5-hydroxytryptamine (5-HT)) is an important neurotransmitter that regulates multiple events in the central nervous system. Many of the 5-HT functions are mediated via G protein-coupled receptors that are coupled to multiple heterotrimeric G proteins, including Gs, Gi, and Gq subfamilies (Martin, G. R., Eglen, R.

The concept that a guanosine triphosphate (GTP) binding protein (or G protein) is a transducer of receptor-to-effector signal transduction was formulated in the 1970s for hormonedependent adenylyl cyclase. It has been shown that binding of the hormone to the receptor triggers exchange of guanosine diphosphate (GDP) for GTP on the G protein, thereby converting the G protein from the inactive con...
