Proteins and peptides form the cornerstone of cellular function, serving not only as essential catalysts and structural components but also as mediators of signalling and regulation in health and ...

Researchers have identified a new function of a well-known enzyme: the signal peptidase complex is responsible for the quality control of membrane proteins. The discovery of this new function for a ...

How did life originate? Ancient proteins may hold important clues. Every organism on Earth is made up of proteins. Although all organisms—even single-celled ones—have complex protein structures now, ...

Researchers have shown that the formation of biological condensates affects cellular activity far beyond their immediate vicinity. The results show that they may be a previously missing mechanism by ...

Scientists may have figured out a brand new way to treat lung cancer by using a protein that inhibits tumor growth. This previously unknown molecule pathway could help researchers develop personalized ...
