Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables monoamine transmembrane transporter activity; neurotransmitter transmembrane transporter activity; and quaternary ammonium group transmembrane transporter activity. Involved in histamine transport and monoamine transport. Acts upstream of or within several processes, including histamine uptake; quaternary ammonium group transport; and regulation of appetite. Located in several cellular components, including apical plasma membrane; mitochondrial membrane; and neuronal cell body. Is expressed in several structures, including brain; dermis; extraembryonic component; genitourinary system; and thymus primordium. Orthologous to human SLC22A3 (solute carrier family 22 member 3).
