In all living cells, DNA makes RNA and RNA makes proteins. The molecular factory that translates the information from RNA to proteins is called the ''ribosome''. It is a large and sophisticated entity, itself made of RNA and proteins.

Using a novel approach, Matthieu Gagnon and other Yale researchers in the lab of Nobel laureate Thomas Steitz in the department of molecular biophysics and biochemistry have described the crystal structure of the ribosome bound to a new protein, called elongation factor 4 (shown in dark blue), that plays a crucial and heretofore unknown role in production of proteins, which are essential to all life.

The knowledge of the structure sheds new light on the intricate process of producing proteins and also paves the way to creation of more specifically designed drugs.
