Cation and sugar selectivity determinants in a novel family of transport proteins [PDF]

Molecular Microbiology, 1996
A new family of homologous membrane proteins that transport galactosides–pentoses–hexuronides (GPH) is described. By analysing the aligned amino acid sequences of the GPH family, and by exploiting their different specificities for cations and sugars, we have designed mutations that yield novel insights into the nature of ligand binding sites in ...

Structural and biochemical comparison of the FLVCR and CTL membrane protein families in eukaryotes [PDF]

Life Science Alliance
Structure–function analysis supports that the FLVCR membrane protein family acts as choline transporters, whereas a nontransport role is suggested for the CTL membrane protein family, previously proposed to be choline transporters.

Physiological and Putative Organic Cation Transporter Expression Response to Alizarin Dye Exposure in Aedes aegypti Mosquitoes [PDF]

Insects
There remains an urgent need for knowledge regarding the molecular and genetic mechanisms in Aedes aegypti to support the fight against mosquito-borne illness, one of these areas being xenobiotic transport.

The molecular mechanism of fluoride export by the eukaryotic fluoride channel FEX [PDF]

Nature Communications
Much of life on Earth, including plants, fungi, and bacteria, evolved to resist toxic environmental fluoride. In eukaryotes, the major resistance mechanism is fluoride export by membrane proteins known as FEX. Using electrophysiology and transport assays,

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

Angewandte Chemie International Edition, 2021
Abstract 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.

In vitro Assay to Evaluate Cation Transport of Ionophores

Bio-Protocol, 2022
Ion homeostasis is a fundamental regulator of cellular processes and depends upon lipid membranes, which function as ion permeability barriers. Ionophores facilitate ion transport across cell membranes and offer a way to manipulate cellular ion ...

Kidney‐specific expression of a novel mouse organic cation transporter‐like protein [PDF]

FEBS Letters, 1997
Using the signal sequence trap method, we have cloned a novel 12‐membrane‐spanning transporter‐like protein, termed renal‐specific transporter (RST), from the mouse kidney. RST is a 553‐amino‐acid protein highly homologous to recently cloned organic cation transporters, e.g.

Cation permeability in CorA family of proteins

Scientific Reports, 2020
CorA proteins belong to 2-TM-GxN family of membrane proteins, and play a major role in Mg2+ transport in prokaryotes and eukaryotic mitochondria. The selection of substrate is believed to occur via the signature motif GxN, however there is no consensus ...

Genome-wide analysis of the apple CaCA superfamily reveals that MdCAX proteins are involved in the abiotic stress response as calcium transporters

BMC Plant Biology, 2021
Background Calcium (Ca2+) plays an important role in plant growth and development, and the maintenance of calcium homeostasis is necessary for the survival of all plant species. Ca2+/H+ exchangers (CAXs) are a subgroup of the CaCA (Ca2+/cation antiporter)
