Abstract excerpt
The Na+/I- symporter (NIS), the plasma membrane protein that actively transports I- (stoichiometry 2Na+:1I-) in thyroid physiology and radioiodide-based thyroid cancer treatment, also transports the environmental pollutant perchlorate (stoichiometry 1Na+:1ClO4-), which competes with I- for transport. Until now, the mechanism by which NIS transports different anion substrates with different stoichiometries has...
