Biosensors based on membrane transport proteins
Biosensors and Bioelectronics, 1991We propose a novel class of biosensors based on membrane bound receptors or transport proteins as the sensing element. The protein is incorporated in a planar lipid bilayer which covers the transducer. The transducer may detect an electric current, a voltage, or a change in fluorescence.

Protein toxins and membrane transport
Current Opinion in Cell Biology, 1998Recently, protein toxins have provided novel information on the anatomy of the machinery that mediates vesicle docking and fusion with target membranes within the cell. Their use is being extended to the study of the physiology of these processes in different cells and tissues, as well as to the intracellular pathways of membrane transport.

Coat proteins in intracellular membrane transport
Current Opinion in Cell Biology, 1994Transport of newly synthesized material from the endoplasmic reticulum (ER) towards the Golgi complex, through the Golgi cisternae, and out of the trans-Golgi network (TGN) is thought to be mediated by vesicular carriers. Different types of vesicle are involved in this biosynthetic membrane traffic.

Membrane transport proteins: not just for transport anymore
American Journal of Physiology-Renal Physiology, 2006digitalis glucosides have been used for their cardiotonic properties for several centuries. It was not until the 1950s that the molecular target of these compounds was identified as the Na-K-ATPase.

Protein transport across the peroxisomal membrane
bchm, 2009Abstract The maintenance of peroxisome function depends on the formation of the peroxisomal membrane and the subsequent import of both membrane and matrix proteins. Without exception, peroxisomal matrix proteins are nuclear encoded, synthesized on free ribosomes and subsequently imported post-translationally.

Coat proteins: shaping membrane transport
Nature Reviews Molecular Cell Biology, 2003Coat proteins allow the selective transfer of macromolecules from one membrane-enclosed compartment to another by concentrating macromolecules into specialized membrane patches and then deforming these patches into small coated vesicles. Recent findings indicate that coat proteins might also participate in the differentiation of membrane domains within

The relative constancy of the internal environment of the cell is maintained by a variety of transport systems which are located within the membrane. These transport systems serve to regulate the entrance and exit of various solutes concerned with the metabolic activity of the cell.

Lipid modification of proteins and their membrane transport
"Protein Engineering, Design and Selection", 1989An effective method for artificial attachment of lipid anchors to water-soluble proteins has been developed. To this end, a protein molecule is modified in a system of reversed micelles by a water-insoluble reagent, e.g. fatty acid chloride. Fatty acylated proteins acquire an ability to translocate across lipid membranes and penetrate intact cells ...

Electrophysiological Characterization of Membrane Transport Proteins
Annual Review of Biophysics, 2013Active transport in biological membranes has been traditionally studied using a variety of biochemical and biophysical techniques, including electrophysiology. This review focuses on aspects of electrophysiological methods that make them particularly suited for the investigation of transporter function.

Protein transport across the ER membrane
Trends in Biochemical Sciences, 1990Protein transport across the endoplasmic reticulum (ER) membrane may be divided into two phases: an initiation or targeting cycle, which has been fairly well characterized, and the actual transfer of the polypeptide chain through the membrane, the mechanism of which is still unknown.
