Amino acid transport across cellular membranes is mediated by multiple transporters with overlapping specificities. We recently have identified the vertebrate proteins which mediate Na+-independent exchange of large neutral amino acids corresponding to tra ...
Electron crystallography and atomic force microscopy allow the study of two-dimensional membrane protein crystals. While electron crystallography provides atomic scale three-dimensional density maps, atomic force microscopy gives insight into the surface s ...
Proteins from cisplatin treated bacterial cells were partially separated by 1D polyacrylamide gel electrophoresis and analysed by laser ablation inductively coupled plasma mass spectrometry; using peptide fingerprinting methods central to proteomics, the b ...
A highly-sensitive surface fluorescence technique was combined with a powerful method for the oriented reversible immobilization of membrane proteins on oxide surfaces. Affinity and kinetic parameters of the interaction of the receptor and a fluorescent li ...
Tumor necrosis factor TNF can trigger increases in membrane conductance of mammalian cells in a receptor-independent manner via its lectin-like domain. A lectin-deficient TNF mutant, lacking this activity, was able to bind to artificial liposomes in a pH-d ...
Tyrosinase is a type I membrane protein found in melanosomes, which are lysosomal-like organelles and specific for pigment cells. A mutation of mouse tyrosinase, platinum (cp), leads to truncation of tyrosinase's cytosolic tail, and results in misrouting t ...
Glycoprotein-associated amino acid transporters (gpaAT) are permease-related proteins that require heterodimerization to express their function. So far, four vertebrate gpaATs have been shown to associate with 4F2hc/CD98 for functional expression, whereas ...
GAD67, the larger isoform of the γ-aminobutyric acid-synthesizing enzyme glutamic acid decarboxylase, is a hydrophilic soluble molecule, postulated to localize at nerve terminals and membrane compartments by heterodimerization with the smaller membrane-anc ...

The screening of ligands for membrane receptor proteins is central to the discovery of new pharmaceutical drugs. We present a general method to reversibly attach receptor proteins via an affinity tag to a quartz surface and subsequently detect with high se ...
Hemodynamic forces affect endothelial cell morphology and function. In particular, circumferential cyclic stretch of blood vessels, due to pressure changes during the cardiac cycle, is known to affect the endothelial cell shape, mediating the alignment of ...
