Bacterial Membrane Transport Proteins
1976Bacterial transport systems are historically associated with the acceptance of the idea that the crossing of the cell membrane by a physiologically significant solute was mediated by the specialized operation of a protein or an array of molecules including specific proteins.

Transport proteins of the plant plasma membrane
Current Opinion in Cell Biology, 1996Recently developed molecular and genetic approaches have enabled the identification and functional characterization of novel genes encoding ion channels, ion carriers, and water channels of the plant plasma membrane.

Electrophoretic Protein Transport in Gold Nanotube Membranes
Analytical Chemistry, 2003Gold nanotube membranes are ideal model systems for exploring how pore size affects the rate and selectivity of protein transport in synthetic membranes. This is because these membranes have cylindrical, monodisperse pores (the nanotubes) with diameters that can be varied at will from tens of nanometers down to less than 1 nm.

Visualization of membrane-associated folate transport proteins
Advances in Enzyme Regulation, 1989Transport of Methotrexate (MTX) into cells, via the "reduced folate" transport system, is a critical factor in the effectiveness of the drug in cancer chemotherapy, and defective transport is one of the principal types of resistance to MTX. Probes capable of detecting membrane-associated folate transport proteins (ftp's) in individual cells are ...

Water Transport Mediated by Other Membrane Proteins
2017Water transport through membrane is so intricate that there are still some debates. (Aquaporins) AQPs are entirely accepted to allow water transmembrane movement depending on osmotic gradient. Cotransporters and uniporters , however, are also concerned in water homeotatsis.

Glyoxysomal Membrane Electron Transport Proteins
1987Experiments utilizing intact glyoxysomes isolated from castor bean endosperm on Percoll gradients indicate that the membrane NADH:ferricyanide reductase (FCR) and NADH:cytochrome c reductase (CCR) activities are differentially affected by trypsin and may be associated with proton fluxes.

Membrane protein oligomeric structure and transport function
Nature, 1981Proteins which traverse membranes tend to have a dimeric structure in which the dimer is arranged asymmetrically across the membrane with the axis of symmetry perpendicular to the membrane plane. This general structure is well suited to the function of transporting nutrients across the cell membrane.
