Identification and characterization of the three members of the CLC family of anion transport proteins in Trypanosoma brucei. [PDF]

PLoS ONE, 2017
CLC type anion transport proteins are homo-dimeric or hetero-dimeric with an integrated transport function in each subunit. We have identified and partially characterized three members of this family named TbVCL1, TbVCL2 and TbVCL3 in Trypanosoma brucei.

Light-Modulated Cationic and Anionic Transport Across Protein Biopolymers [PDF]

Angewandte Chemie International Edition, 2021
Light is a convenient source of energy and the heart of light-harvesting natural systems and devices. Here, we show light-modulation of both the chemical nature and ionic charge carrier concentration within a protein-based biopolymer that was covalently functionalized with photoacids or photobases.

Picrotoxin Delineates Different Transport Configurations for Malate and γ Aminobutyric Acid through TaALMT1

Biology, 2022
Plant-derived pharmacological agents have been used extensively to dissect the structure–function relationships of mammalian GABA receptors and ion channels. Picrotoxin is a non-competitive antagonist of mammalian GABAA receptors.

Preference of Proteomonas sulcata anion channelrhodopsin for NO3 − revealed using a pH electrode method

Scientific Reports, 2021
Ion channel proteins are physiologically important molecules in living organisms. Their molecular functions have been investigated using electrophysiological methods, which enable quantitative, precise and advanced measurements and thus require complex ...

Anion Transport Using Core Functionalized Hyperbranched Polymers and Evidence of a Dense Packed Limit Based on Molecular Weight

Molecules, 2021
Being able to bind, select, and transport species is central to a number of fields, including medicine, materials, and environmental science. In particular, recognizing a specific species from one phase and transporting it across, or into another phase ...

Structural and functional properties of the transporter SLC26A6 reveal mechanism of coupled anion exchange

eLife, 2023
Members of the SLC26 family constitute a conserved class of anion transport proteins, which encompasses uncoupled transporters with channel-like properties, coupled exchangers and motor proteins.

Mutations conferring SO4 2− pumping ability on the cyanobacterial anion pump rhodopsin and the resultant unique features of the mutant

Scientific Reports, 2022
Membrane transport proteins can be divided into two types: those that bind substrates in a resting state and those that do not. In this study, we demonstrate that these types can be converted by mutations through a study of two cyanobacterial anion ...

A Balance between Transmembrane-Mediated ER/Golgi Retention and Forward Trafficking Signals in Glycophorin-Anion Exchanger-1 Interaction

Cells, 2022
Anion exchanger-1 (AE1) is the main erythroid Cl−/HCO3− transporter that supports CO2 transport. Glycophorin A (GPA), a component of the AE1 complexes, facilitates AE1 expression and anion transport, but Glycophorin B (GPB) does not.

Monomeric erythrocyte band 3 protein transports anions. [PDF]

Proceedings of the National Academy of Sciences, 1991
The anion transport system of the human erythrocyte membrane was reconstituted in egg phosphatidylcholine membranes by using either the unmodified transport protein, band 3, or covalently crosslinked band 3 dimers. Unilamellar vesicles of a diameter of 32 +/- 3 nm were then isolated from the sample by passage through a French press and subsequent gel ...
