Structural basis of proton-coupled potassium transport in the KUP family [PDF]

open access: yes, 2020
Potassium homeostasis is vital for all organisms, but is challenging in single-celled organisms like bacteria and yeast and immobile organisms like plants that constantly need to adapt to changing external conditions.

Substrate-bound outward-open structure of a Na+-coupled sialic acid symporter reveals a new Na+ site

open access: yesNature Communications, 2018
Many pathogenic bacteria utilise sialic acids as an energy source or use them as an external coating to evade immune detection. As such, bacteria that colonise sialylated environments deploy specific transporters to mediate import of scavenged sialic ...

About P systems with symport/antiport [PDF]

open access: yesSoft Computing, 2004
It is proved that four membranes su±ce to P systems with minimal symport/antiport to generate all recursively enumerable sets of numbers. It is also proved that P systems with symport/antiport without maximal par- allelism are equivalent to partially blind counter automata.

Gating Topology of the Proton-Coupled Oligopeptide Symporters [PDF]

open access: yesStructure, 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.

Expression of sodium-iodide symporter in thyroid gland tumors: immunohistochemical study [PDF]

open access: yesМорфологія, 2009
One of the key moments of radioiodine therapy, and also radioisotope diagnostics of cancers of a thyroid gland is ability of their cells to accumulate iodide.

High-Throughput Screening and Quantitative Chemical Ranking for Sodium-Iodide Symporter Inhibitors in ToxCast Phase I Chemical Library.

open access: yesEnvironmental Science and Technology, 2018
Thyroid uptake of iodide via the sodium-iodide symporter (NIS) is the first step in the biosynthesis of thyroid hormones that are critical for health and development in humans and wildlife.

Proton-coupled sugar transport in the prototypical major facilitator superfamily protein XylE. [PDF]

open access: yes, 2014

A potassium-proton symport in Neurospora crassa. [PDF]

open access: yesThe Journal of general physiology, 1986
Combined ion flux and electrophysiological measurements have been used to characterized active transport of potassium by cells of Neurospora crassa that have been moderately starved of K+ and then maintained in the presence of millimolar free calcium ions.

Astrocytes and neurons communicate via a monocarboxylic acid shuttle [PDF]

open access: yes, 2020
Since formulation of the Astrocyte-Neuron Lactate Shuttle (ANLS) hypothesis in 1994, the hypothesis has provoked criticism and debate. Our review does not criticise, but rather integrates experimental data characterizing proton-linked monocarboxylate ...

[18F]Tetrafluoroborate ([18F]TFB) and its analogs for PET imaging of the sodium/iodide symporter

open access: yesTheranostics, 2018
Sodium/iodide symporter (NIS)-mediated iodide uptake in thyroid follicular cells is the basis of clinical utilization of radioiodines. The cloning of the NIS gene enabled applications of NIS as a reporter gene in both preclinical and translational ...
