Phosphorylation regulation of nitrogen, phosphorus, and potassium uptake systems in plants

open access: yesCrop Journal, 2023
The uptake of ammonium, nitrate, phosphorus, and potassium ions by roots is mediated by specific ion transporter or channel proteins, and protein phosphorylation regulation events occurring on these proteins and their regulators determine their ultimate ...

Inhibitor binding mode and allosteric regulation of Na+-glucose symporters. [PDF]

open access: yes, 2018
Sodium-dependent glucose transporters (SGLTs) exploit sodium gradients to transport sugars across the plasma membrane. Due to their role in renal sugar reabsorption, SGLTs are targets for the treatment of type 2 diabetes.

Ion channel–transporter interactions [PDF]

open access: yesCritical Reviews in Biochemistry and Molecular Biology, 2016
All living cells require membrane proteins that act as conduits for the regulated transport of ions, solutes and other small molecules across the cell membrane. Ion channels provide a pore that permits often rapid, highly selective and tightly regulated movement of ions down their electrochemical gradient.

Depletion of Tissue-Specific Ion Transporters Causes Differential Expression of PRL Targets in Response to Increased Levels of Endogenous PRL

open access: yesFrontiers in Endocrinology, 2018
Prolactin (PRL) has been considered a key regulator of ion uptake in zebrafish. The genes slc12a10.2 and slc12a3, which are Na+ and chloride Cl− co-transporters, have been reported to be regulated by PRL in freshwater fish. The integrative network of PRL

Anion transport and GABA signaling

open access: yesFrontiers in Cellular Neuroscience, 2013
Whereas activation of GABAA receptors by GABA usually results in a hyperpolarizing influx of chloride into the neuron, the reversed chloride driving force in the immature nervous system results in a depolarizing efflux of chloride.

A Guide to Human Zinc Absorption: General Overview and Recent Advances of In Vitro Intestinal Models [PDF]

open access: yes, 2020
Zinc absorption in the small intestine is one of the main mechanisms regulating the systemic homeostasis of this essential trace element. This review summarizes the key aspects of human zinc homeostasis and distribution.

Using small molecules to facilitate exchange of bicarbonate and chloride anions across liposomal membranes [PDF]

open access: yes, 2009
Bicarbonate is involved in a wide range of biological processes, which include respiration, regulation of intracellular pH and fertilization. In this study we use a combination of NMR spectroscopy and ion-selective electrode techniques to show that the ...

Relocation of active site carboxylates in major facilitator superfamily multidrug transporter LmrP reveals plasticity in proton interactions [PDF]

open access: yes, 2016
The expression of polyspecific membrane transporters is one important mechanism by which cells can obtain resistance to structurally different antibiotics and cytotoxic agents.

A Missing Link in Radial Ion Transport: Ion Transporters in the Endodermis

open access: yesFrontiers in Plant Science, 2019
In higher plants, roots have important functions, such as the acquisition of water and ions, as well as transportation into the aerial parts of the plant via the xylem vessels.

Mechanisms of CFTR Functional Variants That Impair Regulated Bicarbonate Permeation and Increase Risk for Pancreatitis but Not for Cystic Fibrosis [PDF]

open access: yes, 2014
CFTR is a dynamically regulated anion channel. Intracellular WNK1-SPAK activation causes CFTR to change permeability and conductance characteristics from a chloride-preferring to bicarbonate-preferring channel through unknown mechanisms.
