FAMILY

ligand-gated ion channel (TC 1.A.9) family

DESCRIPTION

Also known as 5HT3A_MOUSE, Htr3a, 5ht3, Htr3. This is one of the several different receptors for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. This receptor is a ligand-gated ion channel, which when activated causes fast, depolarizing responses in neurons. It is a cation-specific, but otherwise relatively nonselective, ion channel. Forms pentahomomeric complex as well as pentaheteromeric complex with HTR3B; homomeric complex is functional but exhibits low conductance with modified voltage dependence, and decreased agonist and antagonist affinity. Interacts with RIC3 (By similarity).
