Understanding the Complex Architecture of the Minor Spliceosome

In human cells, only a small proportion of the information written in genes is used to produce proteins. How does the cell select this information? A large molecular machine called the spliceosome continuously separates the coding and non-coding regions of our genes – and it's doing this even as you read these lines.

PanK4 Protein Could Be Key to Better Control of Blood Sugar and Metabolism

Physical activity is not only important for fitness, but also for health. This is confirmed by a new study conducted under the direction of Prof. Dr. Maximilian Kleinert at the German Institute of Human Nutrition Potsdam-Rehbrücke (DIfE). His team discovered that the protein PanK4 plays a crucial role in the energy metabolism of skeletal muscles.
