Studying the complex mechanisms of transducing an extracellular signal across a plasma membrane to initiate an intracellular responce is of fundamental importance for a cell’s function. Transmembrane signaling is the key allowing cells to sense and communi ...

Cheap and massively parallel methods to assess the DNA-binding specificity of transcription factors are actively sought, given their prominent regulatory role in cellular processes and diseases. Here we evaluated the use of protein-binding microarrays (PBM ...

Olfactory receptors (ORs) constitute the largest family of sensory membrane proteins in mammals. They play a key role within the olfactory system in recognizing and discriminating a nearly unlimited number of structurally diverse odorous molecules. The mol ...

Tissue transglutaminase (tTGase) catalyzes both deamidation and transamidation of peptides and proteins by using a peptidyl glutamine as primary substrate. A precise consensus sequence for the enzyme is unknown and the ratio between deamidated and transami ...

The function of membrane proteins is best understood if their structure in the lipid membrane is known. Here, we determined the structure of the mouse serotonin 5-HT3 receptor inserted in lipid bilayers to a resolution of 12 Å without stabilizing antibodie ...

The method analyzes biological fluids collected from patients, and uses attenuated total reflecting (ATR) sensors and spectral analysis by Fourier transform infrared spectroscopy (FTIR) to form a spectral fingerprint of extracellular vesicles (EVs) isolate ...

We report on a generic method to detect and iden- tify the molecular profile of exosomes either derived from cultured cell lines or isolated from biofluids. Exosomes are nanovesicles shed by cells into their microenvironment and carry the molecular identit ...

Neurotransmitter-gated ion channels of the Cys-loop receptor family mediate fast neurotransmission throughout the nervous system. The molecular processes of neurotransmitter binding, subsequent opening of the ion channel and ion permeation remain poorly un ...

Cellular signaling is classically investigated by measuring optical or electrical properties of single or populations of living cells. Here we show that ligand binding to cell surface receptors and subsequent activation of signaling cascades can be monitor ...

Cells secrete extracellular vesicles (EVs) into their microenvironment that act as mediators of intercellulard communication under physiological conditions and in this context also actively participate in spreading various diseases. Large efforts are curre ...
