The birth and death of proteins in a single cell

The amount of proteins inside cells fluctuates over time, and this affects various functions of the cells. Cells are constantly synthesizing and degrading proteins, and studies have shown that this "see-saw" effect actually ...

Scientists discover a molecular timer based on stalling ribosomes

A molecular biologist from Lomonosov Moscow State University and international colleagues discovered a special mechanism of protein synthesis regulation that they called a "molecular timer." It controls the number of protein ...

Nano-switches in the cell

Mitochondria, best known for their role as cellular power plants, perform numerous vital tasks in the cell. During cell respiration, reactive oxygen species can be formed in mitochondria. If these are present in excess, their ...

Maximum precision in protein synthesis

Researchers from the Center for Molecular Biology of Heidelberg University (ZMBH) and the German Cancer Research Center (DKFZ) have investigated the mode of action of a molecular chaperone vital to protein synthesis. Together ...

A protein that extends life of yeast cells

To understand and control aging is the aspiration of many scientists. Researchers at the Biozentrum of the University of Basel have now discovered that the protein Gcn4 decreases protein synthesis and extends the life of ...
