The 5-HT2C receptor also known as 5-hydroxytryptamine receptor 2C is a G-protein coupled receptor in the serotonin receptor family. It has a mass of approximately 51 kDa. This receptor primarily expresses in the central nervous system including regions like the choroid plexus. Researchers note the 5-HT2C receptor's significant presence in areas responsible for regulating mood and cognition making it a critical player in neurotransmitter systems.

Biological function summary

The 5-HT2C receptor plays a role in modulating neurotransmitter release. It is not part of a multi-subunit complex; instead it directly interacts with G proteins to exert its function. Upon activation by serotonin the receptor can influence the release of other neurotransmitters such as dopamine and norepinephrine. This interaction impacts various physiological processes including appetite control mood regulation and anxiety management.

Pathways

One finds the 5-HT2C receptor involved in the serotonin signaling pathway contributing to mood and behavior regulation. The receptor links to the phosphatidylinositol signaling pathway where it engages proteins like phospholipase C. This connection is important for cellular responses to external stimuli. The 5-HT2C receptor also has relationships with other serotonin receptors like 5-HT2B which share similar signaling mechanisms within these pathways.

The 5-HT2C receptor has associations with conditions such as depression and obesity. Its regulatory role in neurotransmitter release influences mood disorders by affecting serotonin levels. Research has shown that the receptor connects with proteins like dopamine transporter which are relevant in the context of psychiatric disorders. In obesity altered receptor activity may affect appetite and energy balance contributing to weight regulation challenges.
