Membrane proteins are proteins found in cell membranes, either at the surface or on intracellular organelles. Integral membrane proteins such as receptors and ion channels span the membrane.

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

The research focus of Kaspar Locher and his group is the structural and mechanistic investigation of integral membrane proteins facilitating active transport processes or membrane-associated ...

Transport across membranes All cells are enclosed by a cell membrane, which is selectively ... DNA and the production of proteins DNA carries the genetic information in the cells of all living ...
