Sodium-iodide symporter

特許 係属中 A sodium/iodide symporter (NIS), also known as a sodium/iodide cotransporter[1] or solute carrier family 5, member 5 (SLC5A5) is a protein that in humans is encoded by the SLC5A5 gene.[2][3][4] It is a transmembrane glycoprotein with a molecular weight of 87 kDa and 13 transmembrane domains, which transports two sodium cations (Na+) for each iodide anion (I−) into the cell.[5] NIS mediated uptake of iodide into follicular cells of the thyroid gland is the first step in the synthesis of thyroid hormone.
