Cation Effects on Protein Conformation and Transport in the Na+/Glucose Cotransporter

open access: yesJournal of Biological Chemistry, 1997
Cation-driven cotransporters are essential membrane proteins in procaryotes and eucaryotes, which use the energy of the transmembrane electrochemical gradient to drive transport of a substrate against its concentration gradient. Do they share a common mechanism?

The yeast vacuolar membrane proteome [PDF]

open access: yes, 2009
Transport of solutes between the cytosol and the vacuolar lumen is of crucial importance for various functions of vacuoles, including ion homeostasis; detoxification; storage of different molecules such as amino acids, phosphate, and calcium ions; and ...

The functions of plant cation/proton antiporters

open access: yesBiologia Plantarum, 2018
The cation/H+ exchange is a basic process in transmembrane transport. The acquisition of genome sequences has now established that plants possess genes encoding a large number of cation/proton antiporter 1 (CPA1) proteins, few of which have been ...

Cation-Dependent Binding of Substrate to the Folate Transport Protein of Lactobacillus casei [PDF]

open access: yesJournal of Bacteriology, 1982
Lactobacillus casei cells grown in the presence of limiting folate contained large amounts of a membrane-associated binding protein which mediates folate transport. Binding to this protein at 4°C was time and concentration dependent and at low levels (1 to 10 nM) of folate required 60 min to reach a steady state.

"In vitro" reconstitution of "trans"-Golgi exit and the effect of GAG attachment on protein sorting [PDF]

open access: yes, 2007
The trans-Golgi network is one of the main sorting stations for proteins and lipids in the eukaryotic endomembrane system. Yet, the mechanisms for sorting and transport out of the trans-Golgi network remain poorly understood.

A human transporter protein that mediates the final excretion step for toxic organic cations [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
In mammals, toxic electrolytes of endogenous and exogenous origin are excreted through the urine and bile. Before excretion, these compounds cross numerous cellular membranes in a transporter-mediated manner. However, the protein transporters involved in the final excretion step are poorly understood.

The isolated ER-Golgi intermediate compartment exhibits properties that are different from ER and cis-Golgi [PDF]

open access: yes, 1991
A procedure has been established in Vero cells for the isolation of an intermediate compartment involved in protein transport from the ER to the Golgi apparatus. The two-step subcellular fractionation procedure consists of Percoll followed by Metrizamide

Structure of cytosine transport protein CodB provides insight into nucleobase‐cation symporter 1 mechanism [PDF]

open access: yesThe EMBO Journal, 2022
Abstract CodB is a cytosine transporter from the Nucleobase‐Cation‐Symport‐1 (NCS1) transporter family, a member of the widespread LeuT superfamily. Previous experiments with the nosocomial pathogen Pseudomonas aeruginosa have shown CodB as also important for the uptake of 5‐

A novel erythroid anion exchange variant (Gly796Arg) of hereditary stomatocytosis associated with dyserythropoiesis

open access: yesHaematologica, 2009
Background Stomatocytoses are a group of inherited autosomal dominant hemolytic anemias and include overhydrated hereditary stomatocytosis, dehydrated hereditary stomatocytosis, hereditary cryohydrocytosis and familial pseudohyperkalemia.Design and ...
