Htr3a - 5-hydroxytryptamine (serotonin) receptor 3A

Enables identical protein binding activity. Predicted to be involved in several processes, including chemical synaptic transmission; positive regulation of ion transmembrane transporter activity; and regulation of membrane potential. Predicted to act upstream of or within ion transport. Predicted to be located in several cellular components, including axon; cleavage furrow; and neuronal cell body. Predicted to be part of serotonin-activated cation-selective channel complex. Predicted to be active in neuron projection and synapse. Predicted to be integral component of plasma membrane. Is expressed in several structures, including central nervous system; eye; gallbladder; genitourinary system; and gut. Human ortholog(s) of this gene implicated in irritable bowel syndrome. Orthologous to human HTR3A (5-hydroxytryptamine receptor 3A). [provided by Alliance of Genome Resources, Apr 2022]
