Description

5-hydroxytryptamine (serotonin) receptor 3A

Gene Summary

Enables identical protein binding activity and ligand-gated monoatomic ion channel activity involved in regulation of presynaptic membrane potential. Involved in inorganic cation transmembrane transport and serotonin receptor signaling pathway. Part of serotonin-activated cation-selective channel complex. Is expressed in several structures, including central nervous system; eye; gallbladder; genitourinary system; and gut. Human ortholog(s) of this gene implicated in alcohol dependence; cocaine dependence; heroin dependence; irritable bowel syndrome; and nicotine dependence. Orthologous to human HTR3A (5-hydroxytryptamine receptor 3A). [provided by Alliance of Genome Resources, Jul 2025]
