It takes more than the genetically coded sequence for a membrane protein to fold and function. Its lipid environment also plays a role.
A protein that provides a vital passage through a bacteriums outer cell wall will misfold and malfunction if that wall is built of the wrong material, scientists at The University of Texas Medical School at Houston report in a finding that has long-term implications for understanding diseases caused by misfolded proteins such as cystic fibrosis, Alzheimers disease, and mad cow disease.
The paper in todays Journal of Biological Chemistry by Professor of Biochemistry and Molecular Biology William Dowhan, Ph.D., and colleagues shows that phospholipids, which make up the permeable barrier of cell membranes, play a direct role in the folding of membrane proteins – proteins that penetrate the membrane or bind to either side of it.

Max Planck researchers revel the nano-structure of molecular trains and the reason for smooth transport in cellular antennas.
Moving around, sensing the extracellular environment, and signaling to other cells are important for a cell to function properly. Responsible for those tasks...
Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
