A functional superfamily of sodium/solute symporters

Biochimica et Biophysica Acta (BBA) - Reviews on Biomembranes, 1994
Eleven 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.

Uniporters, Symporters and Antiporters

Journal of Experimental Biology, 1994
ABSTRACT 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).

Inhibitors of the Proton-Sucrose Symport

Archives of Biochemistry and Biophysics, 1993
Sucrose 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.

Cloning of the Mouse Sodium Iodide Symporter

Thyroid, 2001
The iodide-concentrating ability of the thyroid gland is essential to the production of thyroid hormone. We report the nucleotide and amino acid sequence of the mouse sodium iodide symporter (mNIS), which mediates this activity within the thyroid gland.

Mechanism of chloride interaction with neurotransmitter:sodium symporters

Nature, 2007
Neurotransmitter: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.

Structural insights into the mechanism of the sodium/iodide symporter

Yearbook of Paediatric Endocrinology, 2022
The sodium/iodide symporter (NIS) is the essential plasma membrane protein that mediates active iodide (I-) transport into the thyroid gland, the first step in the biosynthesis of the thyroid hormones-the master regulators of intermediary metabolism. NIS couples the inward translocation of I- against its electrochemical gradient to the inward transport

The chlorella hexose/H+-symporters

2000
The physiology, molecular biology, and biochemistry of the inducible hexose uptake protein of Chlorella kessleri is reviewed. The protein encoded by the HUP1 gene is the most intensively studied membrane transporter of plants. Responsible for substrate accumulation up to 1500-fold, it translocates one proton together with one hexose, and the cell ...

Sodium/iodide symporter (NIS) and cytokines

Experimental and Clinical Endocrinology & Diabetes, 2001
It has been shown that TSH upregulates rat NIS gene expression in vitro, and this induction can be modulated by cytokines. Analysis of the distribution of rat NIS mRNA ex vivo demonstrated variable levels of NIS transcription in different tissue samples. - IL-1beta and IL-6 have been found to decrease NIS mRNA expression in TSH-stimulated FRTL-5-cells.

P Systems with Symport/Antiport and Time

2006
We consider symport/antiport P systems using the time as the support for the output of a computation. We describe and study the properties of “timed symport/antiport systems”, showing that this new model of membrane systems based on time has more power/flexibility, and thus allows us to improve previous universality results.
