The sodium-iodide symporter (NIS) is an intrinsic plasma membrane protein that mediates active transport of iodide in the thyroid gland and several other extra-thyroidal tissues. This activity has been utilized for many years for imaging the thyroid gland and for treatment of thyroid disease both benign and malignant.

A functional superfamily of sodium/solute symporters
BBA - Biomembranes, 1994Eleven families of sodium/solute symporters are defined based on their degrees of sequence similarities, and the protein members of these families are characterized in terms of their solute and cation specificities, their sizes, their topological features, their evolutionary relationships, and their relative degrees and regions of sequence conservation.

Gating Topology of the Proton-Coupled Oligopeptide Symporters [PDF]
Structure, 2015 Proton-coupled oligopeptide transporters belong to the major facilitator superfamily (MFS) of membrane transporters. Recent crystal structures suggest the MFS fold facilitates transport through rearrangement of their two six-helix bundles around a central ligand binding site; how this is achieved, however, is poorly understood.

Uniporters, Symporters and Antiporters
Journal of Experimental Biology, 1994ABSTRACT Transporters are a diverse group of membrane proteins that facilitate the movement of water-soluble solutes through the lipid bilayer of biological membranes. The least complex transporters are the uniporters (Kakuda and MacLeod, 1994).

Photosynthesis Research, 1992
The heterotrophic tissues of the plant are dependent upon carbon and nitrogen import for normal growth and development. In general, oxidized forms of these essential elements are reductively assimilated in the leaf and, subsequently, sucrose and amino acids are transported to the heterotrophic cells in a process known as assimilate partitioning.

Mechanism of chloride interaction with neurotransmitter:sodium symporters
Nature, 2007Neurotransmitter:sodium symporters (NSS) have a critical role in regulating neurotransmission and are targets for psychostimulants, anti-depressants and other drugs. Whereas the non-homologous glutamate transporters mediate chloride conductance, in the eukaryotic NSS chloride is transported together with the neurotransmitter.

Inhibitors of the Proton-Sucrose Symport
Archives of Biochemistry and Biophysics, 1993Sucrose transporters are important components of the assimilate partitioning pathway in many plants. In the results reported here, we examined the effect of several inhibitors on proton-coupled sucrose transport into plasma membrane vesicles isolated from sugar beet leaf tissue.

Sodium Iodide Symporter in Health and Disease
Thyroid, 2001Radioiodine-concentrating activity in thyroid tissues has allowed the use of radioiodine as a diagnostic and therapeutic agent for patients with thyroid disorders such as well-differentiated thyroid cancer. However, some extrathyroidal tissues also take up radioiodine, contributing to unwanted side effects of radioiodine therapy.
