HTR3C refers to the serotonin receptor 3C, which is a subtype of the 5-HT3 receptor family. These receptors are ligand-gated ion channels that are activated by the neurotransmitter serotonin (5-HT). The 5-HT3 receptors are primarily involved in the central and peripheral nervous systems, playing crucial roles in processes such as mood regulation, anxiety, nausea, and vomiting.
