    Functioni

    Acts as an electrogenic sodium (Na+) and chloride (Cl-)-dependent sodium-coupled solute transporter, including transport of monocarboxylates (short-chain fatty acids including L-lactate, D-lactate, pyruvate, acetate, propionate, valerate and butyrate), lactate, mocarboxylate drugs (nicotinate, benzoate, salicylate and 5-aminosalicylate) and ketone bodies (beta-D-hydroxybutyrate, acetoacetate and alpha-ketoisocaproate), with a Na+:substrate stoichiometry of between 4:1 and 2:1. Catalyzes passive carrier mediated diffusion of iodide. Mediates iodide transport from the thyrocyte into the colloid lumen through the apical membrane. May be responsible for the absorption of D-lactate and monocarboxylate drugs from the intestinal tract. Acts as a tumor suppressor, suppressing colony formation in colon cancer, prostate cancer and glioma cell lines. May play a critical role in the entry of L-lactate and ketone bodies into neurons by a process driven by an electrochemical Na+ gradient and hence contribute to the maintenance of the energy status and function of neurons.11 Publications

    Expressioni

    Tissue specificityi

    Expressed in normal thyroid, localized at the apical pole of thyroid cells facing the colloid lumen, but expression profoundly decreased in thyroid carcinomas. Expressed in normal colon but absent in colon aberrant crypt foci and colon cancers. Present in normal kidney cortex, brain, prostate, gastric mucosa and breast tissue but was significantly down-regulated in primary gliomas, gastric cancer, prostate tumors and breast tumors.10 Publications

    Inductioni

    Down-regulated in some primary cancers; due to aberrant methylation in primary colon cancers, astrocytomas and oligodendrogliomas as well as in cancers of the colon, prostate and gastric regions, and glial cell lines. Expression reactivated on treatment with a demethylating drug, 5-azacytidine.4 Publications

    Miscellaneousi

    Miscellaneous

    Increase of iodide influx inhibited by addition of perchlorate (NaClO4), a competitive inhibitor of iodide uptake catalyzed by sodium iodide symporter (NIS). Cotransport of monocarboxylates and nicotinate strongly inhibited by probenecid, nonsteroid anti-inflammatory drugs (ibuprofen, fenoprofen, ketprofen, naproxen) in a Na+-dependent manner or by prolonged exposure to external concentrations of monocarboxylates.
