The encoded protein is a high-affinity transporter specific to the intake of<unk> .<unk>  transport is not inhibited by other organic cations nor affected by sodium ion concentration; it is stimulated by a proton gradient directed outward, with an optimal pH between 8.0 and 8.5. TC1 is transported to the cell membrane by intracellular vesicles via microtubules.
