HTR3E refers to a specific type of serotonin receptor known as the 5-HT3 receptor, subtype E. Serotonin receptors are a class of receptors that bind serotonin (5-HT) and are involved in a variety of physiological and pharmacological processes. The 5-HT3 receptor is a ligand-gated ion channel that, when activated by serotonin, allows the flow of ions, which can lead to neuronal excitation.
