Latest Transmembrane protein Stories
Strings of all kinds, when jostled, wind up in knots.
A new study suggests that protein knots, a structure whose formation remains a mystery, may have specific functional advantages that depend on the nature of the protein's architecture.
Every living plant cell and animal cell is surrounded by a membrane.
Scientists at IRB Barcelona resolve a three-dimensional structure required for the function of some vital cell transporters which communicate cells with the external environment.
Using a unique and relatively simple cell-based fluorescent assay they developed, scientists have identified a means by which fluoxetine, the active ingredient in Prozac, suppresses the activity of the TREK1 potassium channel.
They say it's the little things that count, and that certainly holds true for the channels in transmembrane proteins, which are small enough to allow ions or molecules of a certain size to pass through, while keeping out larger objects.
Some bacteria react to the cold by subtly changing the chemistry of their outer wall so that it remains pliable as temperatures drop.
A more specific and faster detection of viruses has been identified in new research by Trinity College Dublinâ€™s Professor of Physics, Martin Hegner at Trinity Collegeâ€™s Center of Research on Adaptive Nanostructures and Nanodevices (CRANN) and an international team of researchers.
It's well known that high doses of aspirin can cause ulcers and temporary deafness, but the biochemical mechanism responsible for these phenomena has never been deciphered. New research from Rice University offers clues, showing for the first time how salicylate -- an active metabolite of aspirin -- weakens lipid membranes. Researchers believe these mechanical changes disrupt the lining of the stomach, which functions to protect underlying tissue from the acidic contents of the gut. By a...
