serotonin receptor activity
Definition
Target type: molecularfunction
Combining with the biogenic amine serotonin and transmitting a signal across a membrane by activating some effector activity. Serotonin (5-hydroxytryptamine) is a neurotransmitter and hormone found in vertebrates and invertebrates. [GOC:dos]
Serotonin receptors are a family of G protein-coupled receptors (GPCRs) that mediate the actions of serotonin (5-HT), a neurotransmitter involved in a wide range of physiological processes, including mood, sleep, appetite, and cognition. These receptors are characterized by their seven transmembrane domains, which allow them to bind serotonin and activate intracellular signaling pathways. Serotonin receptor activity is crucial for regulating various cellular functions, including neurotransmission, smooth muscle contraction, and hormone secretion. When serotonin binds to its receptor, it triggers a cascade of events that ultimately lead to changes in cell behavior. These changes can include alterations in gene expression, changes in ion channel permeability, or the activation of other signaling pathways. There are seven main classes of serotonin receptors, each with distinct pharmacological properties and signaling mechanisms. These classes are designated as 5-HT1, 5-HT2, 5-HT3, 5-HT4, 5-HT5, 5-HT6, and 5-HT7. Each class of serotonin receptor is further subdivided into subtypes, with different subtypes exhibiting distinct affinities for serotonin and activating different signaling pathways. For example, the 5-HT1A receptor is coupled to Gi/o proteins and inhibits adenylyl cyclase activity, while the 5-HT2A receptor is coupled to Gq proteins and activates phospholipase C. The diversity of serotonin receptor subtypes allows for the fine-tuning of serotonin signaling in different tissues and cell types. Understanding the molecular functions of serotonin receptors is essential for developing new drugs that target these receptors for the treatment of various diseases, including depression, anxiety, migraine, and obesity. The development of selective serotonin receptor agonists and antagonists has revolutionized the treatment of these conditions, highlighting the importance of understanding the molecular mechanisms underlying serotonin receptor activity.'
