Many central biol. signal transduction processes such as synaptic transmission occur at the level of cell membranes. It is therefore not surprising that the biol. function of membrane proteins in general and neuroreceptors in particular can be modulated by ...
Membrane proteins fulfill many central functions in the biological membrane. The insertion process of these proteins and their structure, which are intimately linked to their function, are not yet well understood. As a model we studied three proteins recon ...
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 ...
The receptor that mediates the specific uptake and intracellular transport of dimeric immunoglobulin A (IgA dimer) in mucosal and glandular epithelia is identical with a transmembrane precursor of secreted secretory component. During transport, the IgA dim ...
During light organ colonization of the squid Euprymna scolopes by Vibrio fischeri, host-derived mucus provides a surface upon which environmental V. fischeri forms a biofilm and aggregates prior to colonization. In this study we defined the temporal and sp ...
Structural information on membrane proteins is sparse, yet they represent an important class of proteins that is encoded by about 30% of all genes. Progress has primarily been achieved with bacterial proteins, but efforts to solve the structure of eukaryot ...
Aerolysin of the Gram-negative bacterium Aeromonas hydrophila consists of small (SL) and large (LL) lobes. The alpha-toxin of Gram-positive Clostridium septicum has a single lobe homologous to LL. These toxins bind to glycosylphosphatidylinositol (GPI)-anc ...
Activation of caspase-1 and subsequent processing and secretion of the pro-inflammatory cytokine IL-1beta is triggered upon assembly of the inflammasome complex. It is generally believed that bacterial lipopolysaccharides (LPS) are activators of the inflam ...
Aerolysin is one of a large group of bacterial proteins that can kill target cells by forming discrete channels in their plasma membranes. The toxin has many properties in common with the porins of the Gram-negative bacterial outer membrane, including an e ...
Cell membrane receptors and ion channels are essential in many different cellular processes. To analyse the activity of membrane proteins in vesicles and biological cells, we fabricated micro- nanostructured chips, enabling the application of electrophysio ...
