G protein-coupled serotonin receptor signaling pathway

Definition

Target type: biologicalprocess

The series of molecular signals generated as a consequence of a G protein-coupled serotonin receptor binding to one of its physiological ligands. [GOC:mah]

G protein-coupled serotonin receptors (GPCRs) are a family of transmembrane proteins that play a critical role in mediating the effects of serotonin (5-HT), a neurotransmitter involved in a wide range of physiological processes, including mood, sleep, appetite, and cognition. The signaling pathway initiated by these receptors can be summarized as follows:

1. **Ligand Binding:** Serotonin binds to its specific GPCR, inducing a conformational change in the receptor protein.
2. **G Protein Activation:** The activated receptor interacts with a heterotrimeric G protein, composed of alpha, beta, and gamma subunits. This interaction triggers the dissociation of the alpha subunit from the beta-gamma dimer.
3. **Second Messenger Production:** The activated alpha subunit, depending on its type (Gs, Gi, or Gq), can activate various downstream effectors:
- **Gs:** Stimulates adenylyl cyclase, leading to increased production of cyclic adenosine monophosphate (cAMP).
- **Gi:** Inhibits adenylyl cyclase, leading to decreased cAMP production.
- **Gq:** Activates phospholipase C (PLC), which hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP2) into diacylglycerol (DAG) and inositol triphosphate (IP3).
4. **Cellular Responses:** The second messengers generated in step 3 trigger a cascade of intracellular events, leading to diverse cellular responses:
- **cAMP:** Activates protein kinase A (PKA), which phosphorylates and regulates various target proteins, including transcription factors, ion channels, and enzymes.
- **DAG:** Activates protein kinase C (PKC), involved in cell growth, differentiation, and survival.
- **IP3:** Binds to IP3 receptors on the endoplasmic reticulum (ER), leading to calcium release into the cytoplasm.
5. **Signal Termination:** The signaling pathway is terminated by mechanisms such as:
- **Serotonin dissociation:** Serotonin detaches from the receptor.
- **Hydrolysis of GTP:** The alpha subunit hydrolyzes GTP to GDP, causing it to reassociate with the beta-gamma dimer, inactivating the G protein.
- **Desensitization:** The receptor can undergo phosphorylation and internalization, reducing its sensitivity to serotonin.

Overall, the G protein-coupled serotonin receptor signaling pathway involves a complex interplay between different proteins and molecules, leading to a wide range of physiological and behavioral effects. The diversity of this pathway, coupled with its involvement in various crucial functions, makes it an important target for therapeutic interventions in a variety of neurological and psychiatric disorders.'

clozapineclozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11. It is a second generation antipsychotic used in the treatment of psychiatric disorders like schizophrenia.

Clozapine: A tricylic dibenzodiazepine, classified as an atypical antipsychotic agent. It binds several types of central nervous system receptors, and displays a unique pharmacological profile. Clozapine is a serotonin antagonist, with strong binding to 5-HT 2A/2C receptor subtype. It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.
