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 ...

Cargo-selective SNX-BAR proteins mediate retromer trimer independent retrograde transport

open access: yesJournal of Cell Biology, 2017
The retromer complex, which recycles the cation-independent mannose 6-phosphate receptor (CI-MPR) from endosomes to the trans-Golgi network (TGN), is thought to consist of a cargo-selective VPS26–VPS29–VPS35 trimer and a membrane-deforming subunit of ...

Similarities and contrasts in the structure and function of the calcium transporter ATP2A1 and the copper transporter ATP7B

open access: yesSubstantia, 2018
Ca2+ and Cu2+ ATPases are enzyme proteins that utilize ATP for active transport of Ca2+ or Cu2+ across intracellular or cellular membranes.1-4 These enzymes are referred to as P-type ATPases since they utilize ATP through formation of a phosphorylated ...

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.

Two Different Zinc Transport Complexes of Cation Diffusion Facilitator Proteins Localized in the Secretory Pathway Operate to Activate Alkaline Phosphatases in Vertebrate Cells*

open access: yesJournal of Biological Chemistry, 2005
Zinc is an essential component for the catalytic activity of numerous zinc-requiring enzymes. However, until recently little has been known about the molecules involved in the pathways required for supplying zinc to these enzymes.

An extracellular cation coordination site influences ion conduction of OsHKT2;2

open access: yesBMC Plant Biology, 2019
Background HKT channels mediate sodium uniport or sodium and potassium symport in plants. Monocotyledons express a higher number of HKT proteins than dicotyledons, and it is only within this clade of HKT channels that cation symport mechanisms are found.

Zinc/iron-regulated transporter-like protein gene family in Theobroma cacao L: Characteristics, evolution, function and 3D structure analysis

open access: yesFrontiers in Plant Science, 2023
The zinc/iron-regulated transporter-like protein (ZIP) gene family first identified in plants is highly distributed in the plant kingdom. This family has previously been reported to transport several essential and non-essential cationic elements ...

Developmental Changes in Hepatic Organic Cation Transporter OCT1 Protein Expression from Neonates to Children [PDF]

open access: yesDrug Metabolism and Disposition, 2017
Organic cation transporter 1 (OCT1) plays an important role in the disposition of clinically important drugs, and the capacity of OCT1 activity is presumed to be proportional to the protein expression level in organ tissues. Knowledge of OCT1 protein expression in children, especially neonates and small infants, is currently very limited.

An efficient strategy for small-scale screening and production of archaeal membrane transport proteins in Escherichia coli.

open access: yesPLoS ONE, 2013
BackgroundMembrane proteins play a key role in many fundamental cellular processes such as transport of nutrients, sensing of environmental signals and energy transduction, and account for over 50% of all known drug targets.

The GARP Complex Is Involved in Intracellular Cholesterol Transport via Targeting NPC2 to Lysosomes

open access: yesCell Reports, 2017
Proper intracellular cholesterol trafficking is critical for cellular function. Two lysosome-resident proteins, NPC1 and NPC2, mediate the egress of low-density lipoprotein-derived cholesterol from lysosomes.
